Hi Al,
Full-size 1/4 wave with Rohn 25 -- about 11 inches on a face -- is about 128
feet tall. Your tower should be pretty close to that, maybe slightly taller.
Common method is to put up 120 feet of tower and then make the remainder a
piece of aluminum tubing clamped to the tower, and adjustable up/down to
resonate the tower.Fastening with a couple of hose clamps will work.
My Rohn 25 for 160 is only 100 feet, and I have a small 6-meter yagi on top
that brings it into resonance on 160.
