[VHFcontesting] 6M and 2M Bandpass Filters

[John O’Mara]

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
