Between the shop and the house with 5 computers I have roughly 600 feet
of the stuff. (Part CAT-5 and part CAT-6) I use the RJ45 connectors.
I've never had any fail, but as you say, it doesn't move once installed.
When I see it used for the antenna control I think of being on the
tower, out in the elements, and moving with antenna rotation.
