Occasionally someone will post here or on other amateur radio forums
coaxial cable for sale. Often unused, left over from a project, on a
reel, pickup only, as-is where-is, cash. If one were to pursue such a
purchase, what would one look for and/or do to validate that the cable
is good?
An eyeball physical inspection of the cable is an obvious thing to do.
One can see the outer layer of cable on the reel and perhaps both ends
of the cable. Is that enough?
Should one make some electrical tests before handing over the cash? What
tests and with what test equipment? A few spot frequencies? Wideband
sweeps? Antenna analyzer? VNA? Transmitter with power meter? Something
else? What would you do if both ends are not available or do not have
connectors?
Is it OK to transport a reel with a few hundred feet (or more) of cable
on its side or should the reel be "standing up" in the bed of a pickup
truck?
What else to look for, think about, consider?
