The further the better. However, I have a 65 footer with a KT34XA on it
about 80 feet from my 200 foot 40 meter tower.
I don't really think there is any minimum distance, as far as interaction
goes. I have my 10 and 20 meter beams vertically spaced around 10-15 feet and
have no interaction when I listen on either band in SO2R.

Stations", and lot's more. Call Toll Free, 1-800-333-9041 with any questions
and ask for Sherman, W2FLA.
