In any event, I don't see how a fan dipole would reduce static any more than a single wire dipole.


I read somewhere that it's a proven scientific fact that wire doesn't know the difference between real ham radio waves and static.  But I may be wrong.   Wink

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed.  Easily done in DSP.

I'm looking into doing this as well .... lexan spreaders and wire

by the way K1JJ .... I ran into mr Vu's cousin at the hamfest .... he said his name was Deja .... it was eerie and had a really peculiar vibe to it

Try downloading the antenna modeling program MMANA-GAL.  It's a very capable program, the only distraction being that the dimensions entered are in meters rather than feet. 

1/2 wave on 80 meters is 40 meters, etc. Sounds like it would be easier.
