Everybody knows That's how it goes Everybody knows Everybody knows loading coils are lossy so it must be true eh? No need to question what "everybody knows" - unless you think outside the box. Well, that's the primary mission of this blog so let's take a look at the proposition that "loading coils are lossy" … Continue reading Loading Coils are Lossy. True or False?

CLEFHW antenna: Ready for Action
In the last post I introduced a crazy, off-the-wall idea for a variation of the popular End-Fed Half-Wave (EFHW) antenna. I called it the CLEFHW - Coil Loaded End-Fed Half-Wave. Its purpose is to allow backpack portable operation of an electrical half wavelength antenna without the need for a tree or pole to suspend a … Continue reading CLEFHW antenna: Ready for Action
A CLEFHW Antenna?
I have been on a quest recently. My objective: to explore strange new antennas and boldly go where no ham has been before. It is not that I particularly seek out the weird and wonderful; instead I try to adapt existing antenna designs using lateral thinking ("ham radio outside the box") to create variations that … Continue reading A CLEFHW Antenna?
The Weather Outside is Frightful – Time to POTA on?
Winter came suddenly to southern Ontario this year - and it hit hard. The Town of Gravenhurst, at the southern end of the popular summer destination of Muskoka was whacked with more than three feet of snow in a single storm. We manage winter very well in this part of the world, but that sudden … Continue reading The Weather Outside is Frightful – Time to POTA on?
The QMX is Full of Holes, Here’s the Essential Fix!
When the design team at QRP Labs (alright, we know that means just Hans) set out to produce a multiband portable transceiver that would be packed with advanced features and could be sold for as little as a meager purse of groats, what was their primary design objective? You can bet your life it was … Continue reading The QMX is Full of Holes, Here’s the Essential Fix!
Op-Ed: Does Making It Easier to Get Licensed Really Grow Our Hobby?
Many, many years ago ... You have probably seen the statement: "ham radio is dying". Is it really dying or just changing? I am a "baby boomer"; I was introduced to the hobby by my grandfather who presented me with a crystal set when I was 9 years old. I spent many, many years as … Continue reading Op-Ed: Does Making It Easier to Get Licensed Really Grow Our Hobby?
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”
