Have a 100 foot roll(approx) of used coax cable which has no markings
printed on it.
Can anyone tell me how I can work out what it might be ? e.g. 75 ohm or
50 ohm or ?
Going by the size it looks similar to 50 ohm but I'm not sure.

Any suggestions would be appreciated.


If it has a solid center conductor, it is almost certainly 75 Ohm. The only
exception I can think of is some weird version of RG58.
