Just another tuppenceworth: I know that coax, Cat5 cables, etc. can survive lots of abuse; been a serial abuser in me time. But occasionally, bending just once round a right angle can get you, even if you straighten it up and pretend it never happened. (Wot, me, guv?) Or maybe it had been bent before it ever reached SHJ towers, and chose, as usual, an unpredicted moment to give up.
I seem to remember some sort of law which governs this...
