Since this thread has been resurrected, I’d like to ask about BNC comms - since I’ve never fully understood why they did not become more widely used than they did. If I understand them correctly they are agnostic - no confusing 240/180 or M vs S cable. And no confusing pin orientations. Simply center conductor to center pin and shield to shell? Is there any equivalent to the 511 to patch BNC comms?
