Does a coax cable pass a stereo signal?

I made a DVD off a VHS tape of the Faith Hill special that was on about
a week ago, and notice that the sound is obviously mono, verified by
looking at the sound track in Soundforge. Both L & R are clearly
identical..

I taped it with a stereo VCR via an antenna going through the coax
input, good strong signal going through a 12db amplifier box. I was
under the impression that all modern tv shows are broadcast in stereo,
is this correct? Doesn't a coax cable pass a stereo signal?

Thanks

 

Practically all TV shows are broadcsted in stereo at least in
USA and many European countries. The coaxial cable can transport
stereo sound if encoded to it in a correct way (there a wide
variery of options how this can be done depending on application,
for example digital S/PDIF signals, FM radio broadcasting stereo,
several different techniques to put stereo sound to TV broadcasting
(both analogue and digital systems, what is used varies form country to country)).

There are ways to transport stereo sound through coaxial cable.
The RF coaxial cable output from most consumer video equipment
are only able to give out mono sound... the reason for this
is that mono sound is considerably cheaper to implement to
RF modulator..
