In my case, a balanced antenna tuner that can handle
the big rig is very limited, like a Johnson kilowatt
match box MIGHT handle it.
While I limit the pep to 1500 watts, the audio
compressor is only so fast and peaks beyond 3kw
likely get through.
AM also demands a high duty cycle with its constant carrier.

Getting the open wire line into the basement shack is
also a problem, with all the metal pipes and ductwork around.

The 20 feet of coax seems to not cause problems at all.
