Thanks for the suggestions.
Putting the A3 on top is out of the question. It is the heaviest of all the
antennas. In fact it weighs more than the other 3 combined.
It will be a christmas tree stack with the A3 on the bottom.
So if I follow the 1/2 wave rule. I can get the following
Start with the A3, 2 feet above the top thrust bearing.
1/2 wave on 6 meters is 3 meters or about 9 feet 10 inches above the A3 that
leaves about 3 feet 2 inches above the 6 meter antenna.
Stick the 2 meter antenna exactly half way between the A3 and the 6 meter
beam and mount the 432 beam on the top.
I have the dual band vertical for 2M/440 but I only use it locally so it is
mounted on top of the garage. The 2 meter beam has both vertical and
horizontal elements for SSB/FM work.
The mast is 25 feet of J55 tubing 1.9 inches OD with a 3/16 inch wall with
10 feet inside the tower running through two thrust bearings, one on top
and another 26 inches above the rotor. Rotor is a 1000DXA
sound like a plan?
