My condo was built in 1978. Its hard to tell if its 6 or 59 unless I poke a hole in the wall to find out. If it's RG59, and I would want to redo some connectors, will a RG6 stripper and connector be compatable with RG59 coming out of the wall? I only plan on using RG6 of course if I ever do in home upgrades. I could probably pay Cox to run new coax from the tap but I'm trying to avoid that if possible. The condo is very picky where cables are run and holes are drilled.
Each cable has a different diameter so mixing connectors won't work.
If you remove a wall-plate, you should be able to remove enough slack to find a stenciling on the side of the cable. If you already have a segment of RG6...such as included in the box containing a modem or set-top box...you could probably do a side-by-side comparison of the 2 cables. RG6 would be thicker than 59.
