[SixClub] antenna distances

Ive heard that too but it seems a tad excessive...since the antennas are
in the Horiz plane and your vertical beamwidth will be MUCH less than
that, 1/2wl seems to be too much spacing....I have never spaced antennas
that far apart...on one stack I did, the 2mtr was less than 2 ft above
the 6m antenna...never noticed a problem...as long as the antennas don't
cause a change in SWR (which would indicate there is an interaction),
there should not be a problem stacking closer.....btw 1/2wl on 6 is 108,
not 55 inches!
