Nice web site, Stan!
One of the pix says you paint your antennas with "icephobic paint". Are you
kidding or is there paint that is less likely to build up ice? Can you give
us details about that?

Those look identical to the ones I made for my 8m 4 Square Towers.
Use G10, not just any fiberglass. The G10 rod is more like $20.00 per foot
retail, unless you do a little searching. The one thing I would do
differently is add a washer over the machined ends of the fiberglass
insulators to put a flat against the unturned portion of the insulator
instead of the sharp edges from the ends of the tower legs. Those sharp
edges can splinter the fiberglass. Also if you span the joint with flat G10
material (maybe 4 inches wide by 18 inches long by 3/8 inches thick) it will
at least reduce if not eliminate the lateral movement.
I have Fiberglas rod guying them now but for many years had four 70 foot
towers unguyed with this setup at the base.
It is interesting that a lot of hams are let's say "thrifty" but when it
comes to having something made or making it themselves to save hundreds or
even thousands of dollars, many will pay whatever it takes to buy the end
product.
