I mounted a CM4228 with amp on my rooftop, but now I need to raise it. The antenna rotor and mount assembly are actually in my attic, with the antenna mast protruding through the roof via a 1" 'plumbing vent' waterproof rubber and aluminum 'flange'. It's a great setup, and this way my amp and rotor are not exposed to the elements (neither are the coax connections). It also helps to keep the neighbor annoyance factor to a minimum.
Now however, I need to raise the antenna up about 6-8' to increase my reception of a local low power DTV broadcast antenna (which my neighbors roof line just barely blocks), and to also reach over the new heater exhaust vent which is just a few feet away. The heater exhaust is located precisely between my antenna and the transmitting tower.
Since the entire shaft and antenna rotate with this setup (the parts sticking through the roof that is), I cannot simply connect some guy wires to stabilize it.
I was wondering if anyone knew of a special guy-wire kit that I could stabilize the mast with when I raise it? I was thinking a 2 part assembly; the top part would have the guy wires attached to it and would twist freely around the mast (like a donut with 3 threaded screws to mount the wires to), and the lower part would clamp to the mast and hold tension from underneath for the wires attached to the top piece.
If this does not make sense, I will post some mechanical drawings when I get a chance.
