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! →

Construction of the Simple Low Profile Multiband POTA Antenna

Following on from the previous post, there seems to be some interest in how the Simple, Low Profile, Multiband POTA antenna was actually built. Although the antenna is described as "simple", that term relates more to how it is deployed and its appearance than its actual construction. The construction does not involve any special tools … Continue reading Construction of the Simple Low Profile Multiband POTA Antenna →

A Simple, Low Profile, Multiband Antenna for POTA

Sometimes it is necessary to set up for a POTA activation in an area where other park users like to go. In this situation we can either entertain distracting inquiries from people passing by who may just be curious about our activity, or blend into the environment and not be noticed. I prefer the latter. … Continue reading A Simple, Low Profile, Multiband Antenna for POTA →

How many truly field expedient ham radios are available? Maybe only 2!

Only two? If you were to ask the military you might get a different answer. Indeed many hams actually use ex-military portable radios, such as the PRC series. Those radios are in a class of their own, but they are often heavy, designed to be carried into the field by fit, strong, young soldiers. But … Continue reading How many truly field expedient ham radios are available? Maybe only 2! →

Does an antenna top hat really work?

Antenna "Top Hat" aka Capacitance Hat There are several ways to shorten a vertical whip antenna, for example, a loading coil, linear loading (folding back all or part of the radiating element) and one that has intrigued me for quite a while - a capacitance hat, also known as a top hat. A top hat … Continue reading Does an antenna top hat really work? →

An Outside the Box version of the Delta Loop antenna

I have written about delta loop antennas before - notably in April 2023 in a post entitled "Delta Loopy Ideas". A few weeks ago I received an email from Alan WA3EKL who suggested I should take another look at delta loops and offered a lot of helpful advice, tips and suggestions for making this type … Continue reading An Outside the Box version of the Delta Loop antenna →

My radio is tiny. So why is my POTA backpack so heavy?

We have mountains in Ontario. We call them mountains, but they are really just small hills. So I have never had to actually hike for miles up steep slopes carrying a backpack with all my radio gear, plus anything else I might need for a mountaintop activation. To all those who operate in this fashion, … Continue reading My radio is tiny. So why is my POTA backpack so heavy? →

Shark’s Teeth and Canadian Jam – a tall story

I recently purchased a Spiderbeam mast from a vendor in the United States. The list price was US$78 - a great price for a high quality product. But the story didn't end there - not by a long shot. The cost for shipping via courier was an additional US$44. I expected there would be more … Continue reading Shark’s Teeth and Canadian Jam – a tall story →
