I just received an email announcement from Chameleon Antenna, and I thought I’d share it here.
I’ve often referred to Chameleon antennas as “military-grade” because I’ve seen numerous military portable antenna systems over the years and Chameleon antennas are engineered to that standard. The quality is simply uncompromising.
Chameleon antennas are at the top of the amateur radio price bracket for portable antennas, but affordable compared to other military field antenna systems.
Their recent email announcement showcased a real-world example of how their antennas are used in military communications exercises. From Chameleon:
For QRPX 2021, the NTC Operations Group, Fort Irwin, CA station had the opportunity to deploy several Chameleon Antenna systems to use in the competition. This article is a summary of how each system performed during the contest, and how each could serve a military operator best.
Every year in mid-March, Army NETCOM hosts an annual HF Low Power Competition where stations across the globe try their best to establish HF communications with each other over a variety of modes, including USB Voice, ALE, 3rd Generation ALE, and Tactical Chat messaging application.
Participants include:
Active Duty, Reserve, and National Guard elements of the US Army
The three Army MARS HF Hubs in Ft. Detrick, MD; Ft. Huachuca, AZ; and Ft. Shafter, HI
Any other military branches including Air Force, Marines, Navy, Space Force, and Coast Guard
Canadian military teams
Army MARS Auxiliarists
As a Signal Coach out here at The National Training Center (NTC), Fort Irwin, CA, I found out about this competition, and competed the last two years. In the 2020 QRPX, I operated my station alone using only an L3Harris AN/PRC-150 with its accompanying antenna, the L3Harris RF-1944 dipole kit. I operated as I was able to, not expecting much, only to find out that my station placed third with 48 points and was only a few contacts shy of the winning score of 53 set by a fully stacked team from Joint Base Lewis-McChord. I was absolutely hooked from there.
I’d recommend you download and read the detailed report.
If you can’t tell, I’m proud to have Chameleon Antenna as a sponsor of QRPer. They’re a brilliant company that designs and builds all of their gear here in the USA. Their gear is built for the long haul. They’ve never heard of the marketing concept “planned obsolescence.” I’m guessing Chameleon’s idea is to impress you enough with their product quality that you buy more and more of their systems.
By the way, if you think I’m supportive of amateur radio manufacturers that build quality products, don’t even get me started about my obsession with US-made backpacks and camping gear. Seriously. Just slowly back away while you can… 🙂
On Monday, March 22, 2021, I performed three QRP field activations in one day. I started off the day with a visit to Three Top Mountain Game Land, and then headed to Mount Jefferson State Natural Area for a POTA and SOTA activation before heading to New River State Park.
When plotting my multi-site activation day, I picked Mount Jefferson because it’s a SOTA entity (W4C/EM-021). I only realized later that it’s also a POTA entity (K-3846). I mistakenly assumed Mount Jefferson was a county park rather than an NC state park. To do both a POTA and SOTA activation simultaneously is ideal!
Mount Jefferson (W4C/EM-021)
This was my first visit to Mount Jefferson and, frankly, I wasn’t sure what to expect in terms of hiking.
The park itself is amazing! North Carolina parks never let me down.
The entrance is near the base of the mountain and very close to the town of West Jefferson. The park road climbs up the side of Mount Jefferson –there are a number of spots to park, hike, and picnic.
I had not checked the trail map in advance, but I had read that the summit trail was accessible from the parking and picnic area at the end (top) of the park road.
I hopped out of my car, grabbed my SOTA pack, and very quickly found the trail head.
The trail is impeccably maintained and wide enough for vehicle use (no doubt these trails double as access for tower maintenance on the summit).
The hike to the summit from the parking are was incredibly short–about .3 miles. Normally, I’d want a much longer hike, but since I was trying to fit three site activations in a span of four hours, I didn’t complain.
On top of the summit, one is greeted by a typical cluster of transmission towers.
While I appreciate checking out antennas and towers, these are never a welcome site because they can generate serious QRM, making a SOTA activation difficult.
I also found a park weather station on the summit. Nice!
I searched around and found a spot to set up well within the activation zone but giving me a bit of distance from the towers.
My Yaesu FT-817ND was desperate to get a little SOTA action, so I decided to pair it with the Chameleon CHA MPAS Lite using the Elecraft T1 ATU to find matches.
After putting the FT-817 on the air, I was very pleased to hear that the nearby transmission towers and power lines weren’t causing any noticeable interference. This was a very good sign because, frankly, propagation was very unstable that day and I had real concerns about being able to work stations on 40 meters.
I hopped on the air and quickly realized I’d forgotten to hook my external battery up to the Yaesu FT-817ND. This meant I was running something closer to 2.5 watts as opposed to a full 5 watts. I decided to attempt the activation without the external battery and add it if needed.
I started operating on 20 meters and was very pleased to quickly rack up a number of contacts. I could tell that most of these contacts were via SOTA because I recognized the calls and primarily SOTA chasers.
Within 11 minutes, I worked 10 stations on 20 meters in CW. I was very pleased with how quickly those QSOs rolled in and how easily I logged the four needed for a valid SOTA and 10 needed for POTA activation–all on 20 meters.
Next, I moved to 40 meters where I worked two stations and 30 meters where I worked one. For sure, 20 meters was a much stronger band than 40 and 30 turned out to be.
After working 13 stations, I packed up.
Obviously, 2.5 watts was plenty for this activation!
I would have loved to stay longer, but frankly, I needed to stick to my schedule because I had one more park to fit in that day! (More on that in a future post and video!).
Here’s my QSOmap for the Mount Jefferson activation:
And here’s my full log:
Video
Even though I was a bit pressed for time, I still made one of my real-time, real-life videos of the entire activation. I hope you enjoy:
Next up will be an activation of New River State Park. I hope to post this early next week.
Last Monday (March 22, 2021), I had another opportunity to play radio for the bulk of the day. These are rare opportunities–although I did have another open day only a few weeks ago–so I ty to take full advantage of them! The weather was perfect, so I decided to make a detour to Ashe County, North Carolina en route to visit my parents.
I haven’t been to Ashe County in the better part of a decade although I love this pretty secluded part of western North Carolina.
Ashe County is very much a destination–not a place you’d easily happen upon in your travels. It’s very much worth the detour, though, as it’s close to Boone/Blowing Rock, the Blue Ridge Parkway, and a number of other spots outdoor enthusiasts would love. The towns of Jefferson and West Jefferson are everything you’d expect from small town NC: charming and friendly. Plus, they have some excellent sources of cheese!
I plotted a three park, one summit run for that Monday. I’d have about one hour at each site, which would hopefully be enough to set up, play radio, and pack up. All three sites were new to me–meaning, I had never personally activated them.
My first destination?
Three Top Mountain Game Land (K-3869)
I left my QTH around 9:00 local and arrived on site around 11:30. I had researched the most accessible parking area (there were many for this game land) and one that would be closest to my other destinations.
The game land maps are pretty accurate, but this parking area was a little tricky to find as it’s small, elevated off the road, and you have to enter a private driveway to find it. the “Hunters Parking” sign is, let’s say, “discreet.”
Honestly? Finding these sites is all part of the fun.
Going into this activation, I knew there would be challenges. For one thing, propagation was similar to the day before: poor and unstable.
Secondly, the Reverse Beacon Network (RBN) auto-spotting functionality on the POTA spots page was not working. That was a bad thing because this game land site had no hint of mobile phone service.
I did anticipate both of these issues though, and took precautions:
I contacted my buddies Mike (K8RAT) and Eric (WD8RIF) and gave them my full schedule with anticipated start times for frequencies at each location before leaving the QTH.
I also had my new Garmin InReach satellite messaging device that I could use to text Mike and Eric should they not be able to hear me that day.
As I’ve mentioned in previous post: successful activations (especially if you’re under time pressure) always include being spotted to the POTA network. It’s as if you don’t exist if you’re not spotted.
“CW ATNO”
Another thing working in my favor at this particular site is that it had only been activated a couple times before and both of those times it was via phone only. My activation would be the first time CW had been used at this site for POTA. This means nothing in terms of the Parks On The Air program–meaning, there are no special awards for this sort of thing–but it does give you a bit of an edge because CW hunters will find the site rare and very desirable. They’ll go the extra mile to get logged.
It’s funny: in 2020, I activated numerous proper ATNOs (All Time New Ones)Â for POTA. There were so many here in western North Carolina that just by going to new sites each time, I ended up activating them for the very first time in phone and/or CW.
POTA grew by orders of magnitude last year, though, and now there are so many activators who would love to be the first to activate a site, new entities are often activated within a day of being added. The only true ATNOs left in NC are game lands that have accessibility issues.
On The Air
I deployed my EFT-MTR antenna that I repaired that weekend. I did a very basic repair, attaching the top end of the radiator back to the in-line coil/trap. Somehow in doing this I changed the antenna enough that my SWR on 40 and 20 meters was in excess of 2.5:1.
No problem: I employed my T1 ATU to bring the SWR back down to 1:1.
I hopped on 40 meters and immediately started working stations. No doubt, the rarity of this park was providing my spot with a little extra attention.
In 23 minutes, I worked a total of 20 stations: that’s about as good as it gets, especially with poor propagation.
Once the initial group of hunters died down, I went QRT.
Normally, I would spend more time on-site and move up the band, but I was on a tight schedule and realized I hadn’t allowed any time to grab a to-go lunch!
Video
I did make another real-time, real-life video of the entire activation from start to finish. If you care to watch it, click this link to view on YouTube, or watch via the embedded player below:
Thanks for reading this report. Three Top was a fun activation and I was very happy I didn’t have to struggle to validate it. The next park that day was Mount Jefferson which also happened to be a SOTA site. I’ll be posting the report and video later this week!
Many thanks to Mike (W6MVT) for sharing the following guest post:
Back to Ham Radio for a Year – A Brief Reminiscence
by Mike (W6MVT)
This story will sound like many I have heard over the past year, but I will write it nonetheless as a note of gratitude.
Last March COVID had just restricted our activities and I was wondering how to spend my time. I had received my licenses back in the 80’s. There was a code requirement, there was no internet, no QRZ, no spotting.
Though I enjoyed ham radio very much, family and work took precedence, and the equipment went into storage. I eventually sold it off (who is dumb enough to sell matching Drakes?).
Fast forward to the around 2010, when I knew I would be retiring and might want to get on the air again. I picked up some used equipment and stashed it away without really using it.
Then 2020 arrived and the world changed dramatically. One day, prompted by who-knows-what, I had the bright idea to dust off the gear and hook it up, mostly to see if it even still worked. A makeshift wire in the back yard and a quick listen and there it was – a CQ.
I was actually nervous to answer – it had been that long. It was KE8BKP, who it turns out, was activating a park. I hadn’t a clue what that meant, but I shakily answered. We exchanged reports and he went on the to the next one. I had two immediate reactions. First, I was reassured by that brief, painless interaction. The stuff worked and I could still “do this.” Second, things had changed a great deal since the “old days.” But I researched POTA and SOTA and DX Clusters and all the other magic that now exists.The point is that POTA gently reopened the door to an amazing hobby, one that still fascinates me. I went on to become an active hunter and now a prolific activator.
Since it has been a year now, I felt it important to acknowledge this moment, and to note one more thing. When an activator answers a call, we don’t know the other person’s circumstances. Maybe they are a new – or returning “old” ham. Maybe it took courage to key the mic or pound the key. I have appreciated the manner in which POTA hams enthusiastically help one another improve, learn and in turn help others. Thanks to Jeff, KE8BKP, and all the others since, and to come. And thanks to the many volunteers that keep the program running each day.
73, and be well,
Mike W6MVT
Mike, I couldn’t agree with you more. I think all POTA, WWFF, and SOTA activators are essentially ambassadors for ham radio. We never know what’s happening on the other end and I strongly believe in patience and understanding when answering calls and performing an exchange. It can have a huge positive impact for the person on the other end.
So glad you found Parks On The Air and that you’re enjoying playing radio once again!
Thank you for designing these apps and sharing them, Craig. I love the simple design–I’m loading this on my iPhone. It’ll make for an easy check before I head to the field for a summit or park activation.
In the case of the iWatch app, I see this being a very “handy” tool! (See what I did there–? Yeah, sorry for that.)
I’d be interested in your thoughts/views/opinion/reasoning for that. I am hoping to get a KX-2 soon and was planning to get the aluminum knob that you recommended.
Excellent question. I did, indeed, swap out the nicer aluminum knob with the stock lightweight knob. I meant to write a quick note about that last year.
I did this after watching a presentation by Wayne Burdick (N6KR) for the QSO Today Expo last year.
Here’s the video queued up to the spot where Wayne mentions why he doesn’t recommend anything other than the stock plastic encoder:
In the video, I believe he’s really referring to heavier encoders rather than the lightweight aluminum one, but I still pulled it thinking I was perfectly happy with the plastic one and would accept the compromise. Anything to extend the longevity of my KX2.
The video is a fascinating look at how the KX2 was designed and developed. I would encourage you to watch the entire video when you have the time.
Chameleon Antenna has sent me a number of their antenna systems to evaluate in the field over the past few months at no cost to me. I appreciate not only the opportunity to test these antennas, but to provide the company with my frank feedback.
As I’ve mentioned previously, Chameleon antennas are military grade and build here in the US (check out Josh’s tour of their factory). You pay a premium price–compared to imported options–but their gear is built for performance, easy deployment, and longevity.
What has impressed me most about Chameleon gear is how flexible and modular it is. Their antenna systems are adaptable to almost any situation and always built around the idea of emergency communications.
Recently, Chameleon sent me their new CHA TDL or Tactical Delta Loop antenna. This vertical loop antenna has been designed to be portable, and tunable from 3.5 to 54.0 MHz (80-6M), but, as Chameleon points out, “is most effective on the bands from 10.1 to 54.0 MHz (30-6M). ”
TDL deployment
If I’m being perfectly honest, I wasn’t sure what to expect this antenna to look like–in terms of size–once deployed, so I set it up in the front yard prior to taking it to the field.
Set up couldn’t have been more simple: attach the 17′ telescoping whips to the stainless steel spike (with one whip attached to the Hybrid Micro), extend the whip sections, then attach the loop wire to connect the tips of both whips.
It might have taken me four minutes to set up the TDL on the first go.
This antenna needs a little space for sure: this isn’t one you could easily deploy in a dense forest, but it has a very flat profile vertically. I can’t think of a single park I’ve activated that couldn’t accommodate the CHA TDL.
I like to try to give gear a fair chance when I do evaluations and thought I’d wait until propagation was at least stable before taking the TDL to the field and making a real-time, real-life video (as I used it for the first time). But, frankly, I’m way to impatient to wait for the sun to play fair! Trial by fire…
Lake Norman State Park (K-2740)
On Monday (March 15, 2021) I packed up the CHA TDL and headed to Lake Norman; one of my favorite parks to play radio.
Propagation left much to be desired that afternoon, but the weather was perfect.
I decided to pair the CHA TDL with my Icom IC-705. Since the CHA TDL requires an ATU, I connected the mAT-705 Plus.
NVIS on the low bands
I had no idea what to expect from the CHA TDL in terms of performance, but Chameleon notes that it provides Near-Vertical Incidence Skywave (NVIS) propagation on 40 and 80 meters. NVIS antennas are very popular for the military and for emergency communications since the propagation footprint is much closer to home than it might normally be.
NVIS is also a brilliant option for park and summit activators, especially if they’re activating in an area with a high density of park/summit chasers. For example, if you live and activate sites in the state of Maryland, employing a NVIS antenna might make your site more accessible to the DC metro area, Pennsylvania, Virginia, New York, Delaware, and New Jersey–regions that might otherwise be in the skip zone of your 40 meter signal.
On the air
Operating five watts CW, I started calling CQ POTA on 20 meters and snagged four stations in about seven minutes.
I was very pleased to work a station in California and one in Montana with five watts. (Though I need to check, this might have been my first MT station logged from a park.)
Next, I moved to 40 meters and was very curious if the TDL would provide me with proper NVIS propagation.
It did! One litmus test for me is when I work stations in Tennessee on 40 meters. Typically, I only log TN stations when on 80 meters or when I’ve configured one of my wire antennas for NVIS coverage.
Here are my logs from this 28 minute activation:
Here’s a QSOmap of the activation–the delineation between my four 20 meter contacts and eight 40 meter contacts is pretty evident:
Video
Here’s my real-time, real-life video of the entire activation which also shows how the CHA TDL easily fit in among trees:
In a future video, I’ll show how I deploy the CHA TDL.
Unfortunately, I left my tripod at home, so apologies for the viewing angle as I operated the IC-705.
Summary
This first test of the CHA TDL really couldn’t have gone better.
I was able to easily deploy it on sloping ground, among trees, in a state park, and snag both locals and QRP DX within a brief window of time on the air. All this, while our local star tried its best to interfere.
In terms of construction, the TDL is what I would expect from Chameleon: military grade.
For park activators and Emcomm purposes, the CHA TDL makes for a convenient, portable NVIS antenna on 40 and 80 meters.
While I have lighter, smaller footprint antenna options for SOTA, I must admit I’m very curious how it might perform on 20 and 17 meters from the summit of a mountain. The idea of being able to rotate the antenna and change the propagation footprint is very appealing. I’ll save this experiment for a summit that doesn’t require hours of hiking, though, and one where I know I can jab the stainless steel spike in the ground (i.e. not on top of a rocky mountain).
Any negatives? When I first deployed the TDL at home, we were having 30+ MPH wind gusts. When the gusts shifted, it did move the antenna. This could be remedied pretty easily by using a bit of fishing line filament to tie off one side of the loop. With that said, I’m not sure I’d configure the TDL as a loop if I expected strong winds. Also, as I mentioned earlier, this might not be the best antenna to pack if you plan to include a multi-hour hike in your activation.
And herein lies the brilliant thing about Chameleon Antennas: If I packed in the CHA TDL and found that winds were strong on site, I would simply configure it as a vertical instead of a loop!
The CHA MPAS Lite vertical
The CHA TDL can easily be configured as a CHA MPAS Lite portable vertical: all it’s missing is a counterpoise wire which you can buy separately from Chameleon or, better yet, just use some spare wire you have on hand!
Or, you could configure it as a random wire antenna by directly connecting a length of wire to the Hybrid Micro transformer.
That’s the thing about Chameleon HF Antennas: they can be configured so many different ways.
If you’re interested in the CHA TDL, I’d strongly encourage you to read though the user manual: it’s chock full of info and ideas. Click here to download as a PDF.
Next time I take the CHA TDL out, I think it’ll be to a summit where I’d like to see how it might perform on the higher bands with the ground sloping away from the antenna site.

On Monday, March 8, 2021, I had a very rare opportunity: nearly a full day to play radio!
I debated where to go the night before and I had a lot of ideas. Do a multi-park run? Activate some new-to-me parks a little further afield? Hit a SOTA summit?
While it was very appealing to plan a multi-park run for POTA/WWFF, I really wanted to stretch my legs and activate a summit. The weather was glorious and it dawned upon me that we’ll soon be entering the season of afternoon thunderstorms which will, no doubt, have a negative impact on my summit plans for the next few months since afternoons are typically when I have time to do activations.
After examining the map, I decided to go to Elk Knob State Park. The summit of Elk Knob is a SOTA site and the park is in both the POTA and WWFF programs.
The round trip hike to the summit (adding in a little trail loop around the park) would amount to about 4 total miles and an elevation increase of roughly 1,000 feet.
Monday morning, I left the QTH around 9:00 and arrived at the park around 11:15–it was a proper scenic drive.
The 1.9 mile hike to the summit took me about 45 minutes. The path was amazingly well maintained: 4′ wide with crushed stone most of the way.
One of the nicest trails I’ve been on in ages–Elk Knob State Park is quickly becoming one of my favorite NC State Parks.
There aren’t any antenna-friendly trees on the summit, so I was happy that I packed the Chameleon MPAS 2.0.
At first, I planned to only bring the top section of the MPAS 2.0 vertical to save space, but the hike was so short, I brought the lower aluminum sections as well. I’m glad I did.
Deployment of the MPAS 2.0 was quick and I the Elecraft KX2‘s internal ATU found a match on 20 meters very quickly.
Elk Knob (W4C/EM-005)
I spotted myself using the SOTA Goat app and received quite a 20 meter CW pileup! As you’ll see in my video below, it was testing the limits of my CW skills for sure.
With 5 watts, I quickly worked stations to my east in France, Spain, and Germany, and to my west all over the west coast of North America. It was a hoot!
I eventually moved to 40 meters and operated a bit, but 40 was suffering from poor propagation so stations that are normally quite strong, were weak that day.
I needed four stations for a valid SOTA activation and 10 stations for a valid park activation. I logged a total of 38 stations in 56 minutes. 75% of those contacts were on 20 meters.
Video
Here’s one of my real-time, real-life videos of the entire activation (less a small amount I removed while eating a quick bite):
When people tell me running QRP is like “trying to play radio with both hands tied behind your back” I’ll show them this video. 🙂
AGN?
While the hike, the weather, and the signals were all in my favor, I’ll admit I wasn’t on my “A Game” that day. We all have days like this where we struggle to copy, to keep up with the flow of contacts, and to send correctly.
In recent weeks, I’ve gotten a number of emails from readers and viewers who said they had a less-than-smooth SOTA or POTA activation and felt a wee bit embarrassed on the air when they struggled copying.
But you know what?
No worries!!!
This is all about having radio fun in the field, enjoying a hike, taking in the views, and soaking up the beautiful weather! It’s not a contest and we have nothing to prove to anyone.
I can also promise you that any chaser/hunter who has ever activated a field site will completely understand if they have to send their call a couple extra times or if they (heaven forbid!) have to re-send their call after you incorrectly copy a character.
This is totally normal.
Be easy on yourself and enjoy the ride. Even on days when I don’t feel like I’m 100% in the groove, I find doing a summit or park activation clears my mind and resets my soul.
My policy? When a mistake is made laugh it off and move on!
Photos
Here are a few extra photos from the Elk Knob hike:
On a gray Friday afternoon last spring, Steve Galchutt sat high atop Chief Mountain, an 11,700-foot peak along Colorado’s Front Range. An epic panorama of pristine alpine landscape stretched in almost every direction, with Pikes Peak standing off to the south and Mount Evan towering just to the west.
It was an arresting view, and the perfect backdrop for a summit selfie. But instead of reaching for his smartphone, Galchutt was absorbed by another device: a portable transceiver. Sitting on a small patch of rock and snow, his head bent down and cocked to one side, he listened as it sent out a steady stream of staticky beeps: dah-dah-di-dah dah di-di-di-dit. “This is Scotty in Philadelphia,” Galchutt said, translating the Morse code. Then, tapping at two silver paddles attached to the side of the radio, he sent his own message, first with some details about his location, then his call sign, WG0AT.
At this point, a prying hiker could have been forgiven for wondering what, exactly, Galchutt was doing. But his answer—an enthusiastic “amateur radio, of course!”—would likely only have further compounded their confusion. After all, the popular image of an amateur-radio enthusiast is an aging, armchair-bound recluse, not some crampon-clad adventurer. And their natural habitat is usually a basement, or “ham shack,” not a windswept peak in the middle of the Rockies.
Galchutt fits part of this stereotype—he’s 75—but the similarities end there. An avid hiker and camper, his preferred shack is atop a mountain, and the higher the summit, the better.
Another rapid-fire burst of dits and dahs sprung from the radio. “Wow!” Galchutt said, “Spain!”
Nearby sat Brad Bylund (call sign WA6MM) and Bob and Joyce Witte (K0NR and K0JJW, respectively). Together, the four are part of a group called Summits on the Air (SOTA), an international, radio version of high pointing. […]
