Hi Richard,
Yeah, at 23 ft. it's a bit low for good 20 meter operation. The 19 ft.
Radio Shack mast sits in a pipe cemented into the ground with 4 ft. below
ground and 4 above. There's a hole through the pipe and when the mast is
extended and lifted up a bolt is slid into the hole and the base of the mast
sits on the bolt, about 2 1/2 ft. above ground level.
A channel Master TV rotor and short mast stub puts the boom at the towering
height of 23 ft. I'm sorry now that I didn't get the 36 ft. mast while RS
still sold them. Channel Master has 30 or 40 footers and maybe in the
future I'll go that route.
It's guyed at 2 levels and in 4 directions using black Dacron rope. Some
of the rope is rated at 900+ pounds and some is the next size larger. Has
held up well in ice and strong winds. This type of mast must be guyed.
73, Steve KW3A
