A recent innovation that I overlooked is the SteppIR antenna. Many
government installations can us a SteppIR instead of a big log-periodic,
reducing installation cost from near or in the six-figure range to less than
$25k while dramatically lowering the profile of the hardware. This was
developed by amateurs for amateurs.
In fact, I believe the word "crazy" was used to describe the idea
originally, but Mike and John Mertell made it work.
