Ham Radio continues to change. Whether you believe the changes are good or bad depends on a lot on your perspective. But, no matter if you are a traditional brass pounder, or you believe the Internet is the future of ham radio, one question stands out as we enter another year.

A Year End Compendium of Outside the Box Antenna Ideas
We have reached the end of another year of crazy ideas here at Ham Radio Outside the Box and a repeat of last year's severe winter has gotten underway in southern Ontario.

I have tried … Continue reading A Year End Compendium of Outside the Box Antenna Ideas
4:1 Balun or 4:1 Unun – how to choose?
Perhaps one of the greatest confusions in the hobby of ham radio is wrapped around the subject of baluns and ununs. What are they, where should they be used and what do they do? At Ham Radio Outside the Box several antennas that need a 4:1 impedance matching device have been described. Since I had … Continue reading 4:1 Balun or 4:1 Unun – how to choose?
A simple outside the box fix for a broken telescopic whip
"If it ain't broke, don't fix it" Or conversely, if it is "broke" you have two choices. Order a replacement from the other side of the planet, and wait for the slow boat from China to navigate thousand of nautical miles across the stormy waters of international seas.

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?
