I am thinking of changing the top of my T antenna to a folded dipole or perhaps multiple folds (zig zagging backwards and forwards to improve the top loading and move the current antinode higher up the vertical. The idea is that the folds should be in series rather than parallel. With 5 lengths of 100 metres or 10 lengths of 50 metres, one could have a quarter wave up in the sky. Does anyone have access to a program or can point me to one, which would allow me to model an antenna of this type? 73s John, G4CNN. _______________________________________________________ Get 100% FREE Internet Access powered by Excite Visit http://freeworld.excite.com
