Topband: Balloon-supported verticals

[Tom Rauch]

I tried the half-rhombics Herb describes at a FM BC station located 
in a swap in the 70's.

I had two of them with reversible terminations. They were real dud's.

I also tried modelling them on EZNEC in hopes I could install some 
here, and was never able to find a height and length combination 
that showed any gain except straight up. It sort of confirmed my 
70's experience.

If anyone successfully models an antenna like this PLEASE let me 
know in e-mail! Maybe I've been doing something wrong.

 
73, Tom W8JI
