And, BTW, it should be surge-protected where it comes into the building.
Most people forget about it and so it's a "sneak path."

Subject: Re: [TowerTalk] Garage door opener rotator
I'm curious about this fear of 110(120v) on towers. I have done commercial
work on towers and as someone correctly stated, the lights are 120 minimum,
some 240v. Also, at K2GL's place back in the late 70's / early 80's, we
had a rotor for the 4 el KLM 80 @ 200' that was run on 240v. This thing
weighed in at 600lbs! Sheesh! What a job that was getting it up there!
It was built to fit into Rohn 80 and did. The rotor control box used a
beautiful selsyn operated indicator and huge open frame relays switching
the 240v. The mast in this rotor was 5"dia. 1/2 wall steel. I believe it
was really meant to turn military type log periodics.
The point is, 120 or any other voltage needs to be installed safely. On a
tower, that means in conduit with appropriate clamps. Either rigid steel
pipe (preferred) or with EMT and compression fittings to reduce water
problems and water resistant (outdoor) boxes and housings.
