[TowerTalk] Tram Antenna Balancing

[Phil Camera]

What have others done here to "balance" an antenna while using a single line tram?

I put up my big 40M yagi using a two wire tram but antenna balance became an issue even with that setup.  Go to my website, link below, and click on the Antennas button in the upper left for piks and description.

My antenna wanted to just flip the entire two wire tram over so what we did was to use barbell weights (2.5 and 5 pounders) attached at the appropriate place along the boom.  Problem realized was that the attachment point was further out than we could reach once all were at the top of the tower.  Quick thinking led us to hang the weight off the boom using electric fence wire (strong and stiff) and ran that loop through the end of a wood piece (1.5 x 1) which was taped onto the boom and the end of the wood ended up at the tower.  Once all was up, we untaped the wood and pulled the barbell along the boom to us at the tower and then lowed it via the rope pulley used to haul up tools and haul down the tram.  Slicker than anything.  I think there is a picture of the setup.
