[TowerTalk] Commscope SFX-500 cnnectors

[Chuck Dietz]

The UHF to N male are especially prone to breaking at the swivel joint. I
had to temporarily substitute an N connector Stackmatch using 4 Uhf to N
adapters purchased locally and all eventually separated at the swivel joint
just from wind action.  Mail ordered some good ones and had no more
problems.
