Greetings all, Could anyone enlighten me ? : Is there any practical reason
that free standing towers utilised in a gamma match configuration are not
used for 4 squares ? Locally there are heaps of old free standing tv towers
that are around the 50 ft mark

I don't know that Array Solutions still carries the 80m vertical. ZeroFive
Antennas http://www.zerofive-antennas.com sells one that looks very
similar to the Array Solutions freestanding vertical for $2200. I built a
54' freestanding vertical at P40A for considerably less. For K1TTT's
installation, I would consider using 3" diameter aluminum tubing guyed at
two levels. The larger top sections will improve the bandwidth and I think
it's a strong antenna than can be built for a reasonable price. I believe
that K4JA built his 80m 9 circle vertical array this way.

I believe that Array Solutions also has full sized 80m verticals.
