Well, here it is. It's a 5 foot tripod with 10 foot of 1-7/8" EMT .090 wall mast with a Yaesu G-450 rotor. The antenna will be a Cushcraft A148-20T yagi.
This will be going on the peak of my roof which is 37' high. My house is 120+ years old. The roof rafters are 16 on center and are beefy Oak rafters, that are like 3"x6". It's a shingle roof which replaced slate. I have a roofer buddy doing the install.
The rotor weighs 7.7 lbs. The antenna weighs 7.0 lbs. I'm using a 3' piece of 1"-1/4 fiberglass shovel handle that's wood filled.
The mast sticks up 6 feet past the top of the tripod. Of course, I'd like to keep the entire length of EMT mast, but I feel compelled to shorten it due to the laws of physics. I have made a few dry runs dropping the mast with rotor and antenna down into the tripod. It's fairly easy, but I'll be standing on the peak when the final install happens. That might be hairy. The legs will be wider when on the peak. So far, it seams like it's fairly stout. My buddy has installed a few of these. He said if installed correctly, they are pretty stiff. I wanted a Glenn Martin roof tower, but I'd have to buck up the rafters. I ain't into that.
I'm open to any suggestions, concerns, encouragement. I'm thinking of cutting the mast down a few feet, but not sure how much, as I want as much as possible. I might want to replace the beam with a 10 meter quad.
