- Hi Pete, I'd rather say how low is low enough.... When a tower is self resonant the current distribution is linear and a pure voltage shunt feed will drop into a folded unipole. When the radiator is

- Hi All, I thought about Earl, K6SE, and his model last night. Not having the programs Earl has available, I did find something similar in W4OQ's original article. I do vote for a good vacuum capacito

- Fascinating, Earl, and thanks for doing all that work! My NEC-2 model (EZNEC 1.0) probably incorporated all the inaccuracies that you anticipated, because I used a 12" "wire" 97 feet tall for the tow
