If the coax is soaking most of the transmit power it doesn't really
matter what impeadance it is. An SWR meter will still show no
reflected power, hence a 1:1 ratio.


Hmmm.. that sounds a little doubtful to me. If a coax gets a short,
it reflects plenty before the short. If a coax gets an open, it
reflects plenty before the open.... If a coax gets a 50 ohm lossy
resistance, then it soaks up all the power with no reflection.

That's where I'm coming from...
