I would definitely use a stronger tower. The five foot spacing between the
40m and 20m beams will cause some interaction and it should be modeled
before proceeding. Also the lower antenna at 73 inches elevation is too low
:) If you were to place the lower 20m antenna at 75 feet it would likely
hit your 86 foot guy wires when rotating.

Subject: [TowerTalk] Antenna loads for rohn 45

Can anyone tell me what kind of antenna load I can stack on Rohn 45?
I am looking at 130' of tower with a 4 element (full size) 40 Meter at the
130
foot mark but would like to stack 6X6 60ft boom 20 meter antennas one at 135
the other at 73". The phyllistran guys would be at 43 86 and 129 more or
less.
Would adding a 4th set of guys make a difference? then the would be at
32,64,96, & 128. Replay to ab8al@yahoo.com.
Thanks,
Terry
