Experiments with portable, base station and highly unusual antennas

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 →

Random Wire Antennas – A Challenge to Common Knowledge

A random wire antenna's feedpoint impedance is 450 Ohms: True or False? It must be written on a stone tablet somewhere that an end-fed random wire antenna should be fed through a 9:1 impedance transformer. Common knowledge says a 9:1 transformer, in conjunction with a tuner will bring the impedance of a random wire antenna … Continue reading Random Wire Antennas – A Challenge to Common Knowledge →

How Does the Speaker Wire “No Counterpoise Antenna” Work?

Fellow blogger Craig WB3GCK recently posted an account of his build of the speaker wire "No Counterpoise Antenna" and I was immediately intrigued. In fact I rushed out to the store and bought myself a couple of 50ft rolls of 18AWG speaker wire to experiment. After a couple of days of intense backyard wire whispering … Continue reading How Does the Speaker Wire “No Counterpoise Antenna” Work? →

A 24ft Snake in my Back Yard – all lies and jest?

A snake in the grass! When singer/songwriter Paul Simon penned the lyrics to "The Boxer" in 1970 he may have anticipated my recent experiments with a particularly weird, unbelievable and incomprehensible antenna called "The Snake". A ham hears what he wants to hear and disregards the rest The snake I wrestled for a couple of … Continue reading A 24ft Snake in my Back Yard – all lies and jest? →

A Neat Trick with a 20m EFHW Wire Antenna

One of my favorite YouTube channels comes from the UK-based Waters and Stanton ham radio store. The presenter is Peter Waters G3OJV who delivers the content is a refreshingly unassuming, soft-spoken manner. Although it is a commercial channel, Peter introduces topics that are of general interest to hams with only modest company promotional content. A … Continue reading A Neat Trick with a 20m EFHW Wire Antenna →
