I temporarily guyed mine every section as I went up. It wasn't necessary from a structural standpoint since you can safely go at least three sections above a guy point, but it held the tower sections

Speaking of copperweld, does anyone know a good source of #14, #16 and #18 copperweld with at least 30% copper cladding? I have plenty of larger gauge for antennas, but I need some smaller gauge for

I think about 26 ft. (3 sections with 4 ft. buried in concrete) is about all that is recommended for a freestanding 25G tower, with negligible wind load such as a small TV antenna. With even that the

It is unlikely that the manufacturing plant that draws bare wire from bulk copper ingots is the same one that covers the wire with plastic insulation. In 1974 I purchased the 16,000 ft of #12 bare c

That's exactly what they are now doing with plywood. Last time I went to Lowe's to purchase some 3/8" and 1/2" sheets, the so-called 3/8" was actually 11/32" and marked "approximately 3/8". The "app

But if you could find a fairly large stash of old, unused aluminium house wire, with the insulation intact, it would make good ground radials. The plastic insulation would protect it from reaction w

One of the problems is that aluminium remains in a semi-molten state, even at cold temperatures. With steady mechanical pressure applied, it "flows" away from the pressure points, so it is impossibl
