Jim,
Per a bit of light reading in a VHF book, for vert ants, vertical
separation is crucial. For horizontal antennas, horizontal separation is
important. To me, this indicates a single tower station would have better
luck with VERTICAL antennas.
If you use cross-polarization (one antenna vertical), your requirement
for separation is theoretically reduced.
Anyone ever try this at HF? I have--on 80m--but burned out a RX
attenuator. (Was happy to replace a resistor rather than something more
critical, though!)
