Ive had very good luck with band pass filters from antennas-amplifiers. Even
if they don’t advertise they will custom make it. I have legal limit on the
bottom 4 bands.

Good morning,
I’m part of the W4IY Flagpole Knob VHF Contest Group (FM08jm). We have been
operating from Flagpole Knob continuously for over 30 years. Thanks for all the
Qs.
We experienced higher than normal interference between our 6 and 2M stations
during September last year and I wanted to look into what others may be using
and their experiences with bandpass filters, stubs, etc. to minimize
interference between stations. We are running 500W on 6M and 1.2KW on 2M. We
try to space the antennas as far apart as possible but the the top of the Knob
is only so big.
I appreciate any assistance you can provide. Thanks and 73, JackW4NF
