I have seen two commercial antennas advertised that are each 43 feet tall,
and have no traps/stubs, etc. There appears to be a 4:1 balun at the feedpoint. Mentioned, is the requirement to have a tuner at the driving end of the feedline, and max VSWRs in the 4:1 range. Playing around a bit with EZNEC, the feedpoint impedances over the operating range have some large swings. Can anyone shed light on how effective the antenna should be? Wayne W5GIE |
