[VHFcontesting] 6m Coax Stubs

[Kenneth Silverman]

Has anyone successfully used coax stubs on the output of the 6m amp to
suppress 3rd harmonic interference into the 2m station (M/M station)?  If
so, did you use a single or double stub?

The antennas will be on separate masts, spaced about 40' apart, and 6m will
run about 700w.  In most cases the antennas will side to side and roughly
pointed in the same direction, but the beamwidth of the 6m antenna is wide
enough where the 6m antenna could be pretty much looking into the (side) of
the 2m antenna.

Many thanks, Kenny K2KW
