Antenna Height Matters – True or False?

How often have you read that an antenna should be placed as high as possible - the higher the better? Is it true? My inner skeptic says "hmm, maybe". It's certainly an aphorism that is open to scrutiny. Aphorism? The American Heritage® Dictionary of the English Language defines "aphorism" as: "a tersely phrased statement of … Continue reading Antenna Height Matters – True or False? →

Rebuilding the Winter Rybakov Antenna

Almost a year ago I wrote a post entitled "A Simpler Field Expedient Rybakov Antenna for Winter". It is worthwhile to read that post to understand why I felt it necessary to make a winter version of a proven, tried and trusted antenna. My home turf is southern Ontario, Canada about 200km northwest of Toronto. … Continue reading Rebuilding the Winter Rybakov Antenna →

Can a Drinking Straw Help Tune an Antenna?

A stainless steel drinking straw DIY QRP L-match. We'll get back to the drinking straw question in a moment, but first let me describe another new project that took shape on the Ham Radio Outside the Box workbench recently - a QRP L-match. You may recall that we recently described a Z-match builder project that … Continue reading Can a Drinking Straw Help Tune an Antenna? →

A Deep Dive into the Antenna Called “Long Tall Sally”

Back in the spring of 2024 Ham Radio Outside the Box introduced a very unusual field expedient portable antenna for 20m. It was dubbed "Long Tall Sally" because we took a standard quarter wave ground plane, stretched the vertical radiating element way out of resonance, then restored resonance by shortening the radials. This is what … Continue reading A Deep Dive into the Antenna Called “Long Tall Sally” →

“Old Barebones” – A QRP Z-match Builder Project

I actually don't like Z-matches very much, so why did I build one? I'll get to that in a moment, but first I should explain why I am not a fan of the Z-match. These devices comprise two variable capacitors and one fixed inductor. The fixed inductor limits the tuning range compared to other types … Continue reading “Old Barebones” – A QRP Z-match Builder Project →

The “Titanic” 40m Field Expedient Backpack Portable Antenna

The 40 meter band can be a tricky one for backpack portable operators. The problem is that antennas for that band tend to be large and require a tall pole. In the last post we discussed using a backpack as a support for quarter wave whips or short poles. In that role it is gravitationally … Continue reading The “Titanic” 40m Field Expedient Backpack Portable Antenna →

How to Take Backpack Portable Radio to the Next Level

I know many hams like to operate from inside the comfort of their vehicles. I do too, but only in the depths of winter. Winters in Canada and most of the northern states can often be very challenging so some form of shelter becomes essential. But, in the warmer months (both of them, hi hi) … Continue reading How to Take Backpack Portable Radio to the Next Level →

3 Days, 3 Activations, 3 Antennas

My wife and I enjoyed a short early fall vacation to take advantage of a period of warm, sunny weather. I used the opportunity to attempt some POTA activations and compare the performance of three of my field antennas in challenging propagation conditions. I had several parks on my radar and too little time to … Continue reading 3 Days, 3 Activations, 3 Antennas →

A Poor Ham’s Panadapter

I like to think of them as ham radio fish finders - those neat little waterfall displays on many modern radios. No tuning around listening for signals like in the "good old days", just click on a signal on the waterfall display, throw out your callsign and ya got 'em hooked. I live very close … Continue reading A Poor Ham’s Panadapter →
