Attempting to compensate for large mismatches with an ATU at the tx end
of the feeder may result in an apparently good match, but will in most
cases cause the feeder to radiate.
Exceptions to this are when the feeder is of the balanced variety, eg.
open wire, where the feeder carries a 'balanced' standing wave as a
matter of course.
---------------------------
Actually I believe this is one of the great myths of amateur radio.
Standing waves on the feedline do not create feedline radiation. What
standing waves do is to increase the loss in the feedline. Open wire
feeder is used to reduce feedline loss.
