I am planning to put a box near the top of my tower and use it for various
signal wire connections such as rotator cables, antenna switches etc. My idea
was to pull a multi-conductor cable between my shack and this box, have several
screw terminals in the box to attach whatever I need signal and power for.
(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.)
In order to make the box reasonable water tight I plane to use regular, sealed
feedtrough for the cable. 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.
