If the antenna is 30 ohms or 80 ohms, with some reactance, does the
SWR
meter notice the inexpensive run of supposed 70 ohm coax that you
cadged from the cable tv company?

Of course it doesn't. But at least it does try.

The meter thinks it indicates SWR on the transmission line, whereas it
actually indicates SWR on a long, imaginary, non-existent, 50-ohm line
between tuner and transmitter.

What sort of mess would Laurel & Hardy have found themselves in when
trying to disentangle forward from reflected power?
