There is a tuner built by Plastar which can do this.
This is the AT-AUTO. I have one.
But you cannot locate it at the base of the
big stick outside.
It uses a real variable capacitor and variable inductor rather than switched
fixed values, but it is not made for remote use, not waterproof, and costs
WAY too much money to place out in the yard.
Palstar's new auto tuner can be located and
operated remotely. It will cost over $1500 US.
Ouch.
There are a couple of Auto Tuners here in Europe that can do this too, and
they are weather-proof and built for remote use, but one costs about $2400,
the other $4000+.
I have seen them. Too costly for me.
The coax will normally always be in the equation to some extent.
Luckily if you get the match fairly close to 1:1, it will be negligible.
I agree, but you clearly get my point, that locating
the tuner outside at the foot of the big stick
does render the coax far less a factor than if I
tune it all in the shack.
