I have a Glen Martin 8' roof tower that I use for Field Day. The rotor is "split", with the Az unit inside the tower, and the El unit on an 8' aluminum mast. Prior to dedicating this setup to Field Day, I had it up on my roof mounted on a homebrew non-penetrating roof mount made of aluminum angle, and the thick "rubber" pads they use for commercial nprm's. Sorry I don't have any pictures, but the setup worked great. Now if I just had the *time* to operate more! 73, Jim KQ6EA

I look forward the great pictures!

HI Mike,

We have a cement tile roof, so the usual tripod mounting schemes (big wood bolt into the rafters) wouldn't work. I built my own tripod from 2x4 lumber. The base is an upside down "T", with the tail attached to a vent pipe to keep the whole thing from sliding down the roof, and the two sides placed on small blocks with padding under them to to keep from crushing the tiles. The long piece is 8', with a 4' tail. Rising up from the center is another 4' piece, braced to the 3 sides. I attached the steel mast pole to that, with the rotors on top. The base of the rotors is about 6 or 7 feet off the roof, which is low enough that I can reach the wires, and high enough for the beams to clear the roof on vertical passes. I mounted a gutted electrical box at the base of the mast to house some cable relays

Pictures at http://home.jps.net/~gregd/hamsite.htm. The right-most picture on the 4th row shows the tripod.

Good luck with your project,

Greg KO6TH
