I had my DirecTV dish on the same tower as my beam and the cables were
close and parallel to my feedlines/control cables for 75 feet or so.
Never heard a peep from the DirecTV power supply. There's no reason
that a properly shielded and filtered switching supply should cause
problems anyway. My IC-765 has an internal switching power supply that
is completely quiet on all bands.
