[Antennas] Ladder line feed

[Demetre Koumanakos]

Hi All,

I use a roof mounted Icom AH-4 auto tuner for feeding a vertical 
loop, being in the process of repairing and possibly redesigning
it, I considered feeding it from the top instead of the bottom for
increased performance, the only practical method in my case would 
be using ladder line, but would the AH-4 handle the ladder line as
feed line or as a radiating part of the antenna hence a very strange
lobe ??

Can anyone recommend a user friendly antenna analyzing program ??
