No antenna has, at any time, anywhere in any of our lifetimes, been
"tuned" by an "antenna tuner." So called antenna tuners are 2-port
impedance matching networks ... all of them ... and their job is to
match the impedance on one port to another impedance on the second port,
period. Nothing gets "tuned." They come in a variety of flavors ... a
pair of push-pull 807's with a resonant tank and a link feed to the
antenna on open wire line is one. Everything that happens on the feed
line [regardless of it's construction] is the sole result of the complex
impedance at the antenna feed point and the characteristic impedance of
the feedline. No magic.

Kurt,
We are not tuning the antenna , we are matching the antenna to the coax at the
base of the antenna.

I never use an antenna tuner , on the MF and LF bands realmen use a scopematch
