(Yes, I have a 115 V output in the tower already. It has survived several winters so far. No, I don't have power on it unless I need to.)

My dilemma is: What feed-through do I use for the cables between the rotators and the switches etc and the box? I can add a sealed feed-through each time I need a new connection but that requires me to make a hole in the box and put a sealed feed-through each time. Not a big deal if yuo are on the ground or in your work shop but hanging by one arm, 80 feed up does not appeal to me.

Predrill/pumch many holes, and use rubber plugs in the ones you're not 
using now. Ordinary stoppers would work, or those thin ones you see 
plugging holes in automobile firewalls, etc.
