Phil, that is what got me last summer on my 40 footer. the ropes had = rotten due to UV exposure and the one g5rv did not provide enough support = in the proper directions to keep the tower from twisting and folding over = at the too level. this is about 12 feet up the mast. the base was on my = deck with a flange around its' base about 4 foot above ground level which = puts the roof bracket 16 feet above ground level at the base of the tower. = my lot is sloping so the actual tie down points were also slightly = different as one was across a stream at the back and low point of my = property. A cottonwood tree was used for this point about 8 feet above = ground and kids reach. the other tie downs were on the roof eves of the = house about 12 feet above ground level and 10 feet above the base of the = tower. =20 A good question here is what guy medium (metallic and non-metallic) works = in various situation masts, 25 g etc.?
