[TowerTalk] Feedline for a new tower

[Steve Maki]

LMR400 works well as a rotator loop if you dress it in with a relatively 
large hanging loop. Some setups aren't conducive to such a loop (i.e. 
top set of guys right at the top of the tower, etc). I always have 10' 
of tower above my top guys, so it's no problem.

If you need a tight loop, use RG213 or Davis Buryflex.
