In the world of HAM radio, there are several myths that survive through generations despite them clashing with laws of physics. However it is quite interesting to see how easy is to debunk some of them with very simple experiments.
The radiating line myth
In HAM radio discussions “experts” frequently advise against antennae tuned by a tuner for a list of “technical” reasons. Often, one of them is that due to increased VSWR, the line begins to radiate, causing any kind of interference.
Smartest myths are usually founded on unverifiable facts: people are left to choose whether to believe or not. This one, instead, is very easy to verify with a simple experiment….READ MORE
