Mike,

Some on this list have reported good noise reduction results by using a 
balanced antenna/feedline connected to balanced antenna input.  For 
feedline, twinlead, twinax (data cable), twisted pair, and even cheap CAT 5 
networking cable have been used.  If going this route, make sure that 
connections from antenna relay to RF deck are in original specified 
locations.  There is a "mod" which swapped two of these connectors to 
facilitate unbalanced use of RF deck balanced input.
