You can significantly widen the SWR bandwidth that your radio sees on 80m by
using a coax match. Connect your dipole to a 1/2 WL multiple of 50 ohm coax
and then add a 1/4 WL section of 75 ohm coax. Of course this does not change
the actual antenna's SWR but neither would a remote tuner.
Yes. There's a development of this concept on my website, where the
matching method is used as an example in a tutorial on using SimSmith to
design antenna matching networks.

When I was introduced to the concept by local contesters, they credited
it to Dave Leeson, W6NL. When asked about it, he said the idea was much
older than he was.
