The secret is to mechanically isolate the connectors from any of the
rotational forces. One of our neophytes at W5RRR used LMR-400 in the
VHF/UHF antennas system and the failure was when the cable screwed itself
right out of the soldered connector. One of the well known EME experts told
me cables like this were fine for rotator loops (one loop around the mast)
as long as the connectors were mechanically 'isolated'. Ken K5RG
