I'm probably going to end up with two 60 foot towers, spaced about 100 ft,
one with a 204BA and one with a KT-34A. This should provide some casual
multi-multi fun. Although beams are generally stacked vertically, it
occurred to me that these antennas might be fed in phase to get more gain
on 20 meters.
Would you get real gain from this, or just some "diversity" effects on
receive? Would the Dunestar device be appropriate, or does it need equal
lengths of coax going to each antenna? I assume that even if I didn't
measure the coax cables before putting up the antennas, I could find the
best directions (I assume there would be two good directions, 180 degrees
apart) by turning the antennas and comparing "both" to "either". Then I
could add coax to one antenna's feedline in increments for other directions.
Sounds like a cheap way to get a little punch on 20 meters when needed,
even with short towers. Will it work?
