I've been using LMR-400 with my crankup tower for about 5 years, including
the rotor loop. I've got about 10 runs bundled into a large umbilical cord
with the rotor cable, a heavy cable for the 24V tower lights, and a control
cable. The tower is raised/lowered about once a month on average. The
antennas have been used in contesting, including VHF/UHF, so they've seen a
lot of rotation. The rotor loop is fairly large, sticking out from the tower
about 2'. LMR-400 is stiff enough, especially when multiple runs are
bundled, that the rotor loop doesn't hang. So far, no problems.
