POTA Field Report: Bonneau Ferry Wildlife Management Area (K-3888)

Tuesday last week (December 8, 2020), I was still on a much-needed weeklong vacation near Charleston, South Carolina with my family. We had the day wide-open to enjoy the outdoors and my wife suggested we find a nice park where I could play radio and we could enjoy a picnic.

I looked on the POTA map and chose the Bonneau Ferry Wildlife Management Area (K-3888) primarily because I thought it would be fun to spend some time near a lake.

The drive there was over an hour from where we were staying on John’s Island, but well worth it!

Turns out, it was pretty chilly and windy that day due to a front that had moved through the area during the night. After exploring the area a bit, my wife and daughters decided to enjoy their picnic in the car while I did the activation!

On the air

The spot we found near one of the lakes was ideal for a POTA activation. Although there were numerous large trees that were perfect for wire antennas, I deployed my CHA Emcomm Lite vertical knowing it would also perform well (and it did!)

My entire station!

On The Air

Because the CHA MPAS Lite is so easy to deploy, I was on the air in a matter of minutes. I decided to stake it in the ground next to the water about 50 feet from my operating position under a tree. You can see it in the photo above (it’s rather stealthy!).

I’m not at all bothered by cold weather, but it was windy enough that my hands did get cold.

I started calling CQ around 17:55 UTC and by 18:34 I had logged a total of 21 stations on both 40 and 30 meters.

POTA hunters will often thank me for activating a park. I always tell them “it’s my pleasure.” Because it is! Just check out the view from my shack!

This is why I love POTA and SOTA so much. I’m a firm believer that radios and their operators are meant to be outdoors!


When I operate outdoors, I tune out everything else in the world and just enjoy the radio time and the outdoors. It’s bliss.

I kept my total time on site less than one hour so my family and I could continue  exploring the area and even get a long walk on the beach before sunset.

Here’s a map of the stations I worked with 5-10 watts. Since I discovered this park had never been activated in CW, I made it a CW-only activation:

If you find yourself in the Charleston, SC area, I highly recommend a trip to Bonneau Ferry WMA for some Parks On The Air fun!

CHA MPAS Lite: A military-grade compact field antenna

Note: the following post was originally published on the SWLing Post. 

Chameleon Antenna recently sent me a prototype of their latest antenna: the CHA MPAS Lite.

The MPAS Lite is a compact version of their MPAS 2.0 modular antenna system and designed to be even more portable.

Chameleon Antenna is a specialist antenna manufacturer that makes military-grade, field portable antennas that are low-profile and stealthy. Chameleon products are 100% made in the USA and their customers range from amateur radio operators to the armed forces.

Their antennas are not cheap, but they are a prime example when we talk about “you pay for what you get.” In all of my years of evaluating radio products, I’ve never seen better quality field antennas–they’re absolutely top-shelf.

Zeta

I’m currently in my hometown doing a little caregiving for my parents. I’d only planned to be here for a couple of days, but when I saw that the remnants of Hurricane Zeta would pass directly over us with tropical storm force winds and rain, I stuck around to help the folks out.

Zeta struck quite a blow, in fact. No injuries reported, but over 23,000 of us have been without power for over 34+ hours in Catawba county. With saturated grounds, the winds toppled a lot of trees and damaged power lines.

Yesterday, I wanted to take advantage of the power outage and get on the air. I couldn’t really do a POTA activation because I needed to manage things here at my parents’ house. Plus, why not profit from the grid being down and bathe in a noise-free RF space–?

I decided to set it up in their front yard.

CHA MPAS Lite

I had never deployed the MPAS Lite before, so I did a quick scan through the owner’s manual. Although the MPAS Lite (like the MPAS 2.0) can be configured a number of ways, I deployed it as a simple vertical antenna.

Assembly was simple:

  1. Insert the stainless steel spike in the ground,
  2. Attach the counterpoise wire (I unraveled about 25′) to the spike
  3. Screw on the CHA Micro-Hybrid
  4. Screw the 17′ telescoping whip onto the Hybrid-Micro
  5. Extend the whip antenna fully
  6. Connect the supplied coax (with in-line choke) to the Hybrid-Micro
  7. Connect the antenna to the rig

Although I had the Icom IC-705 packed, I wanted to keep things simple by using the Elecraft KX2 I’d also packed since it has a built-in ATU.

Important: the CHA MPAS Lite requires an ATU to get a good match across the bands.

I wasn’t in the mood to ragchew yesterday, but I thought it might be fun to see how easily I could tune the MPAS Lite from 80 meters up.

I checked the Parks On The Air spots page and saw NK8O activating a park in Minnesota in CW:

He was working a bit of a pile-up, but after three calls, he worked me and reported a 559 signal report. Not bad at 5 watts!

I then moved to 40, 18, and 20 meter and called CQ a couple times to see if the Reverse Beacon Network (RBN) could spot me. I like using the RBN to give me a “quick and dirty” signal report. I was very pleased with the bands I tested:

Those dB numbers are quite good for an op running 5 watts into a vertical compromised antenna.

The KX2 very effortlessly got near 1:1 matches on every band I tested.

Of course, after working a few stations in CW and SSB, I tuned to the broadcast bands and enjoyed a little RFI-free SWLing. Noting 13dka’s recent article, I’m thinking on the coast, the MPAS Lite will make for a superb amateur radio and SWLing antenna.

Durability

Although the remnants of Zeta had effectively passed through the area three hours prior, it was still very blustery outside. I was concerned gusts might even be a little too strong for the 17′ whip, but I was wrong. The whip handled the wind gusts with ease and the spike held it in place with no problem.

One of the things I have to watch with my Wolf River Coils TIA vertical is the fact it’s prone to fall in windy conditions and many ops have noted that this can permanently damage the telescoping whip (the weak point in that system).

I’m pretty certain this wouldn’t happen with the Chameleon 17′ whip–it feels very substantial and solid.

Ready to hit the field with the CHA MPAS Lite!

I’m a huge fan of wire antennas because I believe they give me the most “bang-for-buck” in the field, but they’re not always practical to deploy. I like having a good self-supporting antenna option in my tool belt when there are no trees around or when parks don’t allow me to hang antennas in their trees.

I’ve got a park in mind that will make for a good test of the CHA MPAS Lite: it’s a remote game land with no real parking option. I’ll have to activate it on the roadside–an ideal application for the MPAS Lite.

CHA MPAS Lite: Chameleon designs a new QRP compact portable antenna system

Many thanks to, Don (W7SSB), who notes that Chameleon Antenna has just introduced the CHA MPAS Lite: a modular portable antennas system covering from 6M – 160 meters.

I know a number of participants in the Parks On The Air program who use the CHA MPAS antenna system–the MPAS Lite is the “little brother” of that antenna, according to Chameleon.

Although designed with the new Icom IC-705 and other QRP transceivers in mind, the CHA MPAS Lite can handle up to 100 watts in SSB or 50 watts in CW.

They plan to start shipping the antenna in early November 2020 and the price for the system is $340.00. That may sound like a lot of money for an antenna (it is, let’s face it!) but if you speak with pretty much anyone who owns a Chameleon antenna they’ll tell you it’s worth it. The quality is second to none. I’ve been testing their Emcomm III wire antenna recently and it must be one of the most robust portable wire antenna systems I’ve ever evaluated.

Also, all of their products are designed and manufactured in the USA.

We recently added Chameleon Antenna to our list of sponsors here at QRPer.com. I’m very proud to include them because one of my personal missions is to promote mom-and-pop companies that push innovation here in our radio world! It’s humbling that they support us too.
