[TowerTalk] from towers to shack

[Steven H Sawyers (na0ia)]

Under ground is better for lightning protection. The feed lines and 
control lines, need to go to the base of the tower, through a 
lightning arrestor at the base of the tower), then to the shack. If 
they come off the tower high, then they are at a  portion of the 
whole lightning potential.

Elevated lines of any kind are subject to deer with antlers snagging them.
