Why would reflected power be any more dissipated than forward power?
I would ask the same question. Or, if you had 100 watts going forward from
the transmiter end of the coax on a 100 feet of 3 db loss/100 foot coax, then there is only 50 watts at the
end of the coax. If half of that gets reflected (i.e. 25 watts coming
back) from ant-coax mismatch, then it suffers another 3 db loss by the
time it gets back to the entry point on the coax (or, 12.5 watts +/-). At
the transmitter end, Roger and I are having substantial discussions by
private email.
