[TowerTalk] Source for 20' Mast

[Alan NV8A (ex. AB2OS)]

Well, *I* am planning to have only about 9 feet of mast extending beyond 
the top of my tower. The Township Code permits 70 feet, so I will use a 
60-foot tower, plus the 9-foot mast extension, on which I expect to 
mount only my 3-el. SteppIR and perhaps a VHF/UHF beam.

But anyone who wants rotatable stacked arrays or antennas for several 
different bands might need a much longer mast extending beyond the top 
of the tower, unless the tower itself is rotated.

How many antennas can you mount on a 5-foot mast without adverse 
interactions?
