[TowerTalk] Experience with crank up towers....

[Chris]

Jim/Clay,

I have an instruction manual that goes over install, but here's teh condensed version:  When you attach cables to each arm, start with the tower at full height with the cable hanging.  Mark where the cable touches the ground and add two feet for each arm you're attaching (add two feet of slack per arm).  Then lower the tower and attach coax at each arm loosely with zip ties so you can adjust lengths.  Then run up the tower and check positioning, adjust as necessary.  When everything is perfect, tape cables to arm with scotch 33 and you're good to go.  I've never had a problem with snagged cables as the arms keep the cables away from the tower.    AND!  NEVER!  raise or lower a tower without standing right there watching things.  Murphy is always ready to strike when you're not paying attention.
