Steven,
In my opinion: if the input impedance off the amplifier matches the output
impedance of the driver and the coax has excellent shielding, there will be
no problems with any length. When I say "any length", one must be aware of
the coax loss with real long runs.
At 40 feet with something like LMR-400, there should be no problem on HF or
6 meters.
73,
