I lay about a turn and a half around the thrust bearing. Secure the top one
foot above on the mast, the bottom through a compression clamp, the type
with the rubber inserts. The coax only needs to unwind 180 degerrs in each
direction, so it's not under a lot of twist.

This has been a tough one for me. The worst possible arrangement.  The coax
will hang up on the guy wires; and if too close will get into the Tic Ring.
I had both happen. It generally takes a precise length of coax so that
neither happens. You have to experiment.
