Just another data point ...
I believe it is standard for AM broadcast stations to match the tower to the
feedline right at the base of each tower, even with their monster coax or
when they had balanced open feedline. (I worked at one that still had some
remnants of their old open feedline runs.)
Work out a loss budget to see how much power you lose by having a high
feedline SWR.

You shouldn't need any special matching in the shack if you match correctly
at the antenna feedpoint. Just a balun with the right ratio.
