A Linear-Loaded Monopole antenna for hiking

There is a lot of information online about Linear-Loaded Dipoles, but I haven't found anything at all about cutting a Linear-Loaded Dipole in half to create a Linear-Loaded Monopole worked against ground. The legendary L.B. Cebik (W4RNL, SK) published a design philosophy for an 80m Linear-Loaded Monopole, but it didn't match what I had in … Continue reading A Linear-Loaded Monopole antenna for hiking →

The “tootie-toosie” and the Hiking Antenna

My favorite way of operating is to hike into the woods, find a clearing, set up a quick and easy antenna, make one or more contacts and move on. Well, to be honest, I might pause long enough at a back country waypoint to get out my Aeropress and brew up a refreshing cup of … Continue reading The “tootie-toosie” and the Hiking Antenna →

Isn’t every quarter-wave antenna really a half-wave antenna?

It's a bit early for April Fool's jokes so this is a perfectly serious discussion. Just maybe, the distinction between a quarter-wave and a half-wave antenna is a bit more obscure than we thought. Which is better; a quarter-wave or a half-wave antenna? Does it even matter if indeed every quarter-wave antenna really is a … Continue reading Isn’t every quarter-wave antenna really a half-wave antenna? →

A short and maybe not-so-sweet HF antenna

A lot of information has been posted online recently about very short portable vertical antennas. There must be some magic in how they work, surely, since they appear to disobey the laws of physics. I used to own one called a "Miracle Antenna"; it was manufactured in Quebec, Canada. It comprised a 57-inch telescoping whip … Continue reading A short and maybe not-so-sweet HF antenna →

POTA PERformer radials – can we make a compromise?

There has only been one light snowfall in southern Ontario so far this season - just a few centimeters that melted away within a couple of days. In anticipation of upcoming heavier snowfalls and a semi-permanent white blanket that will last until spring, I bravely shrugged off the chilly outside air and set up my … Continue reading POTA PERformer radials – can we make a compromise? →

A Road Trip with the POTA Tripod Antenna – with surprises!

A spell of warm, sunny weather and a chance to get out to see the fall colors in early October prompted my wife and I to go on a road trip up to Ontario's Muskoka region and on to the fabulous Algonquin Park. The park is Canada's largest and oldest and is the home to … Continue reading A Road Trip with the POTA Tripod Antenna – with surprises! →

Two Resonant Simple Wire Antennas for POTA

In essence it is a raised quarter wavelength vertical with 2 above ground radials. A simple idea that Greg has engineered into a rapid deployment, highly efficient, multiband, portable antenna. Greg has backed up his … Continue reading Two Resonant Simple Wire Antennas for POTA →

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 →
