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?

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. http://k5go.com/40-meters/ 73...Stan, K5GO > On Dec 17, 2015, at 10:43 PM, Merv Schweigert <[email protected]> wrote: > > 20 mins work with a 5.00 fibre glass rod spun in a lathe, sort of > grossly overpriced exaggeration of a Rohn insulator. > >> I believe there is a slight misrepresentation here.
