I wonder as well.

For short runs of cable, I highly doubt that using 50ohm vs. 75ohm would
make a difference.  That measurement is a measure of the cable's
impedance over some distance (1000 ft?), so for a short bit of maybe
50-100 ft, the difference *may* be neglible.

Of course, this all depends on how senstive the receiving equipment is,
and I can't make any claims to know how it would really affect the
performance.

The reason you *should* use properly rated cable is because with
impedance matching you can achieve maximum power output.
