[TowerTalk] Tram question.

[n4kg@juno.com]

Greg,

My solution to tramming to the mast is to keep the
tram line somewhat loose to prevent excessive tension.
The ground end is usually well beyond the guy anchors
so a little sag is not a problem.  I like to run the tram
line above one of the guys so that the other two guys
are running away from the tower / antenna, giving me
a little more room to play with.  Also, my top guys are
4 to 7 ft below the tops of my towers to make for 
ease of instillation. I don't have stacked antennas on my 
masts (except for a light 10M beam above a 15M beam).

I use 1/2 inch nylon rope which also stretches somewhat
under load.  The tram line is attached 2 or 3  feet above 
the top of the tower and the pull-up pulley is attached
a few inches above the tram line.

This has worked well for installing 50 to 80 lb. antennas
such as TH6, TH7, Telrex 3L20, CC 4L15, and 5L10's.
A back guy is a good safety precaution but I've never
bent a mast, not even the 1.5 inch mast that carries
my TH6 six inches above an 80 ft TV tower.
