![]() Roof achor points are usually a threaded "hook" or "eye" screw, a nice heavy duty one at least 4 inches long. If it's on one end of your house, then 2 of the points can come back to your roof but the third will have to go off to a tree or down to the ground. ![]() If your antenna is installed in the middle of your roof then this shouldn't be a problem. The "ground end" of the wires typically connect to points on your roof. If you choose wire, use a stranded galanized wire that won't rust. Dacron is widely available at ham stores, ham coax & wire supplies like The Wireman ect. Cotton rope will rot from getting wet & the sun ect.Nylon ski rope will experience UV sun rotting and break down. Your installation will be more or less permanent. Dacron is the only synthetic cord that is impervious to UV rays from the sun meaning the sun will not rot it over time. Dacron is what you see hams using to support their wire antennas. Smaller gauge rope will do but you should use only Dacron. This will keep the ring in place and keep it from sliding down the mast below the point where you need to locate it. You may have to drill a hole through the mast pipe and insert a bolt or something. Then it has smaller holes drilled in it for attaching the guy wires. Probably need to locate the mast-guy connection about 3/4's of the way towards the top.Ī manufactured mast guy ring is a circular piece of metal with a 1 & 1/4" hole in the middle so it fits around standard mast pipe. Typical arrangement is 3 wires, spaced out at 120 degree equal spacing increments (triangular). Yeah you're gonna need need guy wires to go up any higher. RS should have them although I don't have a catalog number for you. Hi MB, there are guy wire kits available at places where you can obtain antenna hardware.
