An Outside the Box version of the Delta Loop antenna
I have written about delta loop antennas before - notably in April 2023 in a post entitled "Delta Loopy Ideas". A few weeks ago I received an email from Alan WA3EKL who suggested I should take another look at delta loops and offered a lot of helpful advice, tips and suggestions for making this type … Continue reading An Outside the Box version of the Delta Loop antenna
Field Day with the POTA Performer
A cold, windy day on the beach at Ainslee Wood Conservation Area on Georgian Bay (part of the Great Lakes) on the first day of the ARRL Field Day 2025. Confession: I am not really a contester, I have far too short an attention span to spend hours sitting in a chair pounding brass. This … Continue reading Field Day with the POTA Performer
An improved tank circuit EFHW coupler
About a month ago Ham Radio Outside the Box posted about "a third way" to match the high impedance at the feedpoint of an End-Fed Half-Wave antenna. A link to the original article is at the bottom of this post. A "30-minute special" was built to prove the concept actually works. It did work fine … Continue reading An improved tank circuit EFHW coupler
My radio is tiny. So why is my POTA backpack so heavy?
We have mountains in Ontario. We call them mountains, but they are really just small hills. So I have never had to actually hike for miles up steep slopes carrying a backpack with all my radio gear, plus anything else I might need for a mountaintop activation. To all those who operate in this fashion, … Continue reading My radio is tiny. So why is my POTA backpack so heavy?
Testing and modifying the “POTA PERformer” antenna
What is the POTA PERformer? Greg Mihran KJ6ER has introduced us to an antenna that he calls the "POTA PERformer". The capitalized PER in its name is an abbreviation for "Portable, Elevated, Resonant". But what is it really? The POTA PERformer is an adjustable elevated vertical radiating whip with two adjustable elevated radials. In concept … Continue reading Testing and modifying the “POTA PERformer” antenna
Reviving a Webster Band Spanner – a 1950s manual screwdriver antenna
About 20 years ago I was approached by a neighbor who, knowing that I am a ham, asked if I might be interested in looking at some of the old ham junque he had accumulated over many years. He was a fine gentleman, in his golden years, who was no longer active in the hobby. … Continue reading Reviving a Webster Band Spanner – a 1950s manual screwdriver antenna
Matching an EFHW antenna – a third way
There is no doubt about the popularity of the End-Fed Half-Wave antenna. It is used by a very large number of hams, especially during portable operations like POTA, SOTA, WWFF etc. Why is it so popular? The principal reason seems to be ease of deployment. The EFHW requires only a single support and can even … Continue reading Matching an EFHW antenna – a third way
I KISSed my Antenna – Here’s Why …
Many years ago I learned about a design technique called KISS. It was an acronym for "Keep It Sweet and Simple". Somewhere along life's journey I started seeing the acronym change to the rather offensive "Keep It Simple Stupid" which I entirely dislike. There are many sound reasons for simplifying a design but none of … Continue reading I KISSed my Antenna – Here’s Why …
What 3 Words? – Maidenhead Grid Squares!
I was taking a walk in a local park recently. The Sydenham river flows through the park and plunges over the Niagara Escarpment creating a local attraction called Inglis Falls. Usually a very pretty sight, but during the spring thaw and following a heavy rainfall, it had become a raging torrent of water that was … Continue reading What 3 Words? – Maidenhead Grid Squares!
