I tend to test. To do that I build and evaluate, its the engineer in me. Over the years the number
of antennas built and tried and tested are numerous. I also look at new and odd as a interesting
challenge to understand it or see if its all that or has a particular characteristic that can be useful.
That and antennas are fun to build.
But there are more than a few that have emerged as goto designs for HF. End feds are one both
resonant and not, full wave loops or rectangles being some.
