Can you explain this? I thought matching the antenna would *exactly*
make the return loss go away because it would eliminate the mismatch.


Not wanting to put words in his mouth....
I read that to mean that the high SWR between the ATU and the antenna
would remain, but the transmitter would be happy with the SWR on the
transmitter/ATU coax.


Are you suggesting the ATU is at the transmitter rather than at the
antenna? The losses are in the coax and transmitter. If the ATU is at
the transmitter you still have coax losses. If the ATU is at the
antenna there are then no losses other than due to non-ideality of the ATU.



It was stated in the original post the ATU is at the transmitter end.
