Oh I see now!!!

Well yeah you would want stranded coax! You need it to flex as the car moves. Laughing

Or stranded Cat5, I think you had high voltage too close for too long.

The enclosure should be rated for harsh environments. And you should maintain adequate spacing between low voltage (CCTV) and high voltage wires or the low voltage wiring should be in a separate metal conduit or tray.

ok. so there are special BNC for stranded. how about RG6 stranded? for combining the power and signal in one cable is not advisable? what are the pros and cons?

For RG-6, you can probably use a BNC designed for 18 gauge solid wire if the RG-6 stranded is 18 gauge total. The only thing is that as the strands get smaller, it becomes more difficult to assemble the connector since the more flexible center conductor sometimes bends before the center pin snaps into the hole. I used to have to pull the pin through with a pair of needle nose pliers when I worked with stranded RG-59. I also sometimes had to cut one strand off to get the wire to fit into the center pin.

I would also bet that compression fittings and 2 piece BNC's would be near-impossible to assemble with stranded wire. You will probably have to use 3 piece BNC's.

Solder-type BNC's are a royal pain. Crimp-type would be easier.
