[TowerTalk] KT34A HF, 70cm, 2m/70cm minimum recommended spacing?

[David Rich]

Hello,

I plan to put up a KT34A tribander and would also like to put a 25
element 70cm beam (K1FO design), and Cushcraft 5 element A270-10S 2
m/70cm above it on a mast with the end mounted Cushcraft at the very
top.  I plan on mounting both VHF/UHF beams vertically polarized above
the tribander.  I use the K1FO design for ATV and the cushcraft for
local repeater work.  What is the minimum spacing that I can get away
with without effecting performance too much?  I read in the ARRL
handbook that the higher frequency beam should be placed multiples of
1/2 wavelength above the lower frequency beam.  This however was
assuming that all the antennas would have the same polarization.

Thanks,
