Antennas: a Riddle Wrapped in a Mystery Inside an Enigma

I owe the title of this post to Sir Winston Churchill who once used it to describe a country that is prominently in the news at the present time. It seemed an appropriate description for ham antennas too because the more I know about antennas, the more I realize how much I don't know. Maybe … Continue reading Antennas: a Riddle Wrapped in a Mystery Inside an Enigma

Building a Manpack – Part 1, the Antenna

To start, let me define what I mean by "manpack". My manpack is a manually transportable, rapidly deployable, field expedient complete radio station for operating while pedestrian mobile or pedestrian stationary . The HFpack group of /PM enthusiasts are the experts in operating Pedestrian Mobile. Personally I prefer the Pedestrian Stationary style of operating. The … Continue reading Building a Manpack – Part 1, the Antenna

A 200ft Wire Antenna Up Zero Feet – How Does it Perform?

One of my local stores was offering 100ft reels of 16ga insulated wire on sale for a good price. I have bought this wire before and was very pleased with its flexibility - an important factor for field portable use where the antenna is subjected to constant winding and unwinding. The wire extends 200ft across … Continue reading A 200ft Wire Antenna Up Zero Feet – How Does it Perform?

How Does a Ground Tuning Unit Work?

I have spent many hours in my reclining thinking chair, posting ideas on the back of my eyelids while contemplating this very question. How indeed does a Ground Tuning Unit (GTU, aka Artificial Ground) actually work? I have a fairly reasonable comprehension of the theory behind antenna tuners, but tuning an entire planet? Now that's … Continue reading How Does a Ground Tuning Unit Work?

A Born Again Miracle Whip

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?
