Thanks to all who answered my question on remote tuners. I have MORE than

Everyone have a GREAT Thanksgiving.

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 is much that is misunderstood about transmission lines by
those who have chosen not to learn the fundamentals. The ARRL Handbook

As one reply says, and in general, remote tuners (matching units) may be
totally un necessary. To learn the truth about feed lines, and see many
persistent myths about feed lines smashed, find and read

Commercial "baluns" are next to useless. I use one of these on all of my
six dipoles.

Looking for input from the collective knowledge of the reflector.
You have a wire dipole for 75 meters fed with a 1:1/5K rated balun. You want to
transition to a remote tuner so you can move around 75/80 meters.
The question is: Do you leave the balun in place, or remove it and feed the
