About 20 years ago a Canadian company, based in Quebec, produced a compact QRP antenna called the Miracle Whip. It was a really good piece of engineering that relied on the principle that a short whip has capacitive reactance that can be cancelled by feeding it through an inductive reactance. Remember, resonance occurs when capacitive … Continue reading A Born Again Miracle Whip

Radio Man Won’t You Come and Fix my Radials?
My humble apologies to the former Canadian folk music band Tanglefoot who came from the general area I live in. I borrowed (and edited) one of their song titles for this post. Just when I thought I had the theory and practice of ground radials down pat, along comes another surprise. After several months of … Continue reading Radio Man Won’t You Come and Fix my Radials?
What in Heaven’s Name is a Rybakov Antenna?
I love to check out interesting, new antenna designs. The Rybakov isn't actually a new antenna, it has been around for a while; either I just hadn't come across it before or I had passed it over and forgotten about it. So when I read about it recently I just knew I had to find … Continue reading What in Heaven’s Name is a Rybakov Antenna?
A Directional Antenna With Just One Straight Wire – Crazy?
Being called crazy is a compliment to my ears. It means I am doing something different, something unusual. I strive to be "crazy" every day. It is only by doing crazy stuff that we innovate and discover new ideas and new ways of doing things. Today I decided to do two crazy things. First, I … Continue reading A Directional Antenna With Just One Straight Wire – Crazy?
A Magic Ground Mobile Antenna
Let me start by confessing; I don't operate HF mobile. So my "mobile" HF antenna is only suitable for stationary "shack-in-a-truck" operations. Driving requires my full attention ... and so does CW operation! I mount one of my two portable vertical antennas on a short aluminum pole which in turn is mounted on the hitch … Continue reading A Magic Ground Mobile Antenna
3 Days, 3 Activations, 2 Parks
It is getting near the end of camping season for 2022. We have one more trip planned for the beginning of October before we winterize the trailer and prepare to hunker down for the long, cold winter. It won't be long before I'll be switching to local park activations in the snow using my radio … Continue reading 3 Days, 3 Activations, 2 Parks
Vertical Antenna Redesigned
I have posted before about my DIY vertical antenna. It is a rapid deployment antenna that has served faithfully for several POTA activations. But, recently I came to realize it wasn't meeting my needs for all three ways in which I needed to deploy it. Time for a redesign! My vertical antenna is a centre-loaded … Continue reading Vertical Antenna Redesigned
Grounds for Improvement
As I write this post my sophisticated home weather station shows the temperature has just edged over the 30 degree Celsius mark. I call it sophisticated because it synchronizes with the US national time standard in Fort Collins, Colorado by receiving VLF (Very Low Frequency) radio signals - without an antenna! Wait a Canadian corn … Continue reading Grounds for Improvement
80m Band Antenna Fits Into Just 1 Square Foot!
Incredible isn't it? But can it really work? "It must be a compromise antenna, or very low efficiency." "Why don't you just put up a good old-fashioned dipole? "One square foot? Are you crazy?" No, we'll yes, I may be a bit crazy but believe me, the performance of my "one square footer" is no … Continue reading 80m Band Antenna Fits Into Just 1 Square Foot!
“The Other Half”
I have a real problem with using vertical antennas when operating field portable. And I mean quarter-wave vertical antennas. You see they need "the other half"; a ground plane, radials, or counterpoise and without "the other half" they just aren't going to work. So here's the rub (as Shakespeare would undoubtedly have commented had he … Continue reading “The Other Half”
