Jim,
Yes, a balanced input can help.
However YMMV.
If you have lots of RF noise hitting your antenna, balancing the feed line is
not going to be the saving grace. I just put up a post earlier about using
some IBM twinax to feed an R390. My noise was from my own equipment in the
garage with my receiver.
The use of a balanced line and dipole antenna helped me with some of the
other neighborhood noise. I was never able to cure it all.
However, the trouble of installing the Twinax between the receiver and a
match box outside where the coax came down from the antenna was really worth the
effort for me. Maybe just getting that much shielded cable as a ground strap
between the receiver and a good ground was as much help as anything.
Been there done that, think it was worth doing.
