Bill,
One point of clarification about my comment. It was specific to the 8
vertical RX array that Bob and I wrote about and was constructed at W5ZN.
The elements were light aluminum tubing (1.25" dia) and each vertical also
has four top hat wires that, aside from providing top loading, also serves
as guys.
I don't expect it to be a problem given my experience with the two permanent
arrays I have erected. But, as I noted in my post, one of this nature has
not yet been tried so much is yet to be learned!
