The single wire tram is a lot more stable than the old two wire and a whole
lot easier to set up.I don't understand why anyone is still using a two wire tram system. I just use the boom to mast clamp u-bolts. ever the size of the boom. I attach the muffler clamps to the boom on either side of the boom to mast plate, and at a tilt such that when the antenna goes up the tram line the 'leading' element tips are pointing up to make sure they clear any guy wires near the top. The rope from the tram pulley is tied to the 'eyes' and adjusted such that the antenna is balanced. I then attach a rudder ( I use a piece If you take the antenna up sideways which makes it a whole lot easier when you get to the top, take the "pull rope", atach it to the boom to mast clamp just like the tram. The run the rope up the nearest element and take a half hitch near the end of the element. Yes it'll make the antenna come up turned a little, but it should be no problem. When the half hitch reaches the mast at the tower, just slide the half hitch down the element toward the boom. When you get to the boom the pull rope can be disconnected. I've used this method with tall gin poles and tall verticals to easily install antennas I'd never be able to do otherwise without a lot of work. 73 Roger Halstead (K8RI and ARRL 40 year Life Member) N833R - World's oldest Debonair CD-2 www.rogerhalstead.com of 1 x 4 wood) to the boom and to the tram line to stop the antenna from twisting while moving up the tram line. This makes raising an antenna a 'piece of cake'! -------------------------------------------------------------------------------- _______________________________________________ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
