[TowerTalk] Greyline Performance antennas

[Gary K9GS]

A better way to describe these is that they are an off center fed vertical dipole. No helical loading. They are working on a 40 ft version. I'm seriously considering a 28 ft one over salt water.   Tuner at the base.73,Gary K9GS

That suggests that they are helically loaded. Vertical dipoles don't need radials. They can center fed or off-center fed. The tallest of these flagpoles, at 28 ft, could work fairly well on 80M. An important caveat though -- field strength from vertically polarized antennas is strongly dependent on soil conductivity. That is, the better the soil in the far field in direction you're trying to work, the better they work.73, Jim K9YC______________________________________________________________________________________________TowerTalk mailing listTowerTalk at contesting.comhttp://lists.contesting.com/mailman/listinfo/towertalk
