The Signal Report

Phillip Sher, AJ6II, needed an antenna his HOA would never notice. He got a flagpole that works 80 through 10 - and a clean lesson in what SWR really means.

He left the towers behind for an HOA. Then K3WA, PVRC president, worked a clean sweep of all 83 CW Sweepstakes sections — on a 20-foot flagpole.

Every operator argues length, SWR, and radials. Almost nobody asks the question that
actually decides who gets out: how much of the radio wave does your antenna grab? That number is aperture, and it is the honest physics behind the five-eighths wave folklore.

The radios in the tent are the same radios on your desk. What changes everything is what is in the air. What Field Day proves, and how to keep it all 52 weekends.

The skeptics are right about end-fed "no radial" verticals -- and the same published authorities exempt the vertical dipole. Two designs, one marketing phrase, and three questions that sort any claim in under a minute.

Ask ten operators where the ATU belongs and you start a decades-old fight. Both camps are right -- for their own stations. Three architectures the published physics supports, the one combination it does not, and the free calculator that settles your case.
