As I stated in an earlier email, I like the idea of having the coax wrapped
around the mast. This seems to be simpler than a loop of coax hanging down
from the boom as a rotor loop, especially if you have 3-4 runs of coax.
For a connection between the coax coming up the tower and the coax coming
down from the beam(s), what I do is put a loop of coax in the line coming
from the beam. Then I connect to a barrel and PL-259. I tape up everything
to a tower leg. This takes the strain off the connection

Subject: RE: [TowerTalk] Making rotator loops separate
This begs the question ..
I am getting ready to stack out and install my first "real" tower and
antenna system in next several weeks and would like to know what is the
correct way to properly install the feedline on a rotating yagi (Force12)? I
see mention of rotor loops and 2 turns around the mast, or single run direct
to balun. I had planned on using a pig-tail of LMR-400 ULTRA-FLEX between
feed (balun) and splice point on vertical run (LMR-400), below rotator. What
is the best way to minimize fatigue on the cable during rotation and
strain-relief the in-line joint? All suggestions appreciated!
