Impromptu POTA activation using the Elecraft AX1 Antenna

8 Comments

A few weeks ago, I posted a report about doing my first park activation with the Elecraft AX1 super compact antenna. If anything, I felt the activation almost went *too* well using such a small antenna. I didn’t want to give others the impression this is all the antenna you’ll ever need–it’s just a brilliant compact antenna designed for convenience and accessibility. It’s a fun field companion and can be used pretty much anywhere.

Yesterday morning, I had a number of errands to run on the south side of Asheville and had not planned to do a POTA activation. While I was waiting on a curbside delivery, however, I was admiring the nice weather and thinking that I might venture out later in the day to do a Parks On The Air (POTA) activation. Part of me knew, though, that if I returned home, I’d get involved with projects and never make it back out to the field.

I always carry a transceiver and antenna in my car, so I opened the trunk and found my Elecraft KX2 transceiver field kit which included the Elecraft AX1 antenna. Technically, that’s a whole station! Why not give it a go–? I’m always up for a challenge.

Since I would be passing by the Blue Ridge Parkway on the way home, I quickly scheduled an activation on the POTA website via my phone so that the spotting system would know to grab my information from the Reverse Beacon Network (RBN) when I started calling CQ.

I knew this might not be an “easy” activation: I would be using a super compact field antenna that’s quite a compromise in terms of performance, propagation wasn’t exactly stellar, and I was activating a popular (hence somewhat stagnant) park on a Monday morning. Not necessarily ideal ingredients for a successful activation.

I also discovered my phone tripod in the trunk of the car, so decided to make one of my real-time, real-life, no edit videos of the entire successful or failed activation. (Hint: It turned out to be a success.)

At the end of the day, the AX1 continues to impress me. It is a compromise? Yes. Does it perform as well as a resonant wire antenna? No. Can it activate a park as well as my other antennas? Yes.

No doubt, part of my success with the AX1 is because I’m primarily using CW instead of SSB to complete activations. I’ve made SSB contacts with the AX1, but I’ve never completed full park activations with it yet–in truth, though, I’ve never tried.

In fact, perhaps it’s just a lucky streak, but so far the AX1 has been as effective as many of my wire antennas in terms of simply completing valid park activations in less than an hour. My signal reports aren’t as strong as they would be with, say, my EFT-MTR resonant antenna or Emcomm III Portable random wire antenna, but it’s enough to get the job done.

If nothing else, I’ll admit that the AX1 reminds me of the magic of low-power radio each time I use it. When I log stations hundreds of miles away, with such a modest station, I feel like I’ve accomplished something.

In short? It’s fun to use.

Black Friday Sale

FYI: I just received Elecraft’s latest Black Friday 2020 ad and noticed that the AX1 antenna package (which doesn’t include the 40M extension) is on sale. Click here to check it out.

Can you activate a park with the Elecraft AX1 portable vertical antenna–?

In my head, this was going to be a post talking about antenna compromise vs. convenience vs. performance. I set out to make a point and will do just that. But it’s not the point I intended to make.

The Elecraft AX1 Antenna

My Maxpedition Fatty Pouch has more than enough room for the AX1, tripod adapter, bipod, antenna, 40M section, and two counterpoises.

For those of you not familiar, Elecraft designed a super compact portable antenna for the KX3 and KX2 called the AX1 a couple years ago. It’s, by far, the most compact HF antenna I’ve ever owned or operated.

What makes it so unique is that no one section of it is longer than 6″, which means when disassembled, it’ll fit in a very small pouch or pocket.

I purchased the AX1 a couple months ago. I bought the antenna, (which handles 20/17 and 15 meters), the 40 meter extension, bipod, tripod mount, and both counterpoises were included.

It’s a cool piece of antenna kit for sure! And so compact!

But let’s face it: it’s a compromised antenna!

An antenna this small and compact is not as efficient as a longer resonant wire antenna. Not even close.

The AX1 wasn’t built for performance per se–although it’s as efficient as it can be for the size–it was built for convenience!

You can set the AX1 up anywhere, anytime.

A POTA Experiment

The AX1 is in the Maxpedition pack on the left, my KX2 in the Lowe pack on the right.

A few months ago, a reader who owns a KX3 asked me if I thought he could successfully activate a (Parks On The Air) park with the AX1.

My reply:

“Sure! Especially if you’re using CW and you have a whole lot of patience.”

Yesterday morning, I decided to test my theory.

I drove to the Blue Ridge Parkway (K-3378) and parked at the Folk Arts Center. I found a picnic table (wasn’t hard at all considering it was hovering around freezing and incredibly breezy!) and set up my station.

It takes me maybe 3 minutes to set up the entire station.

The antenna fits together quickly (I was operating 40 meters, so used the optional extension and 31′ counterpoise).

Three minutes later, I’m ready to rock and roll!

On The Air

I had errands to run in town so didn’t want to spend all day doing this experiment, but I was determined to complete a valid POTA activation which requires 10 total contacts.

Before leaving the house, I scheduled my activation on the POTA site, so it would know to scrape my spot on the Reverse Beacon Network.

Keep in mind, this was taking place on a Monday morning around 10:15 AM and I was activating a park almost every POTA hunter has logged numerous times. The Blue Ridge Parkway is one of the most activated parks in the POTA network, so not exactly super desirable.

In addition, propagation number were pretty dismal.

I fired up the KX2, pressed the ATU button, and achieved a 1:1.1 match.

I called CQ POTA three times in CW.

Evidently, the RBN picked me up quickly, because I received a call.

Then another call.

Then a small pile-up of calls.

Next thing I know, I’ve logged five stations in five minutes.

I called CW again, and had another small pileup.

Short story short, I had achieve a valid activation in all of 12 minutes.

12 freaking minutes!

Seriously? My point was to prove it takes patience when using extremely compromised antennas.

After logging 12 stations, a received a phone call on my mobile and left the air (no other stations were calling me at that point and, again, this wasn’t a highly desirable or rare park). After my phone call, I decided to pack up and finish my errands in town.

After I returned home, I realized: this was easily my quickest field radio deployment and park activation.

The activation took me a total of 20 minutes: 3 minutes to deploy, 12 minutes on the air, and (generously) four minutes to pack up.

Let’s face it…

The stars were aligned Monday morning.

The AX1 is a compromised antenna but it’s obviously also quite effective.

The irony was en route to the activation, I was listening to the latest episode of Ham Radio Workbench. They were discussing wire antennas and how incredibly compromised shortened verticals are.

I was in complete agreement about compact antennas: sometimes, the compromise is worth it for the convenience.

Now, I would add: sometimes, it’s all convenience, performance, and no compromise whatsoever!

Next, I plan to attempt an SSB activation with the AX1. I do believe it’ll take quite a while to gather 10 stations for a valid activation. But who knows?

Stay tuned!
