Does anyone know the UG number for J104, the balanced input connector?        
                       
There are several different balanced connectors and adapters that will fit 
J104. The most useful connector/adapter as far as I am concerned is the 
UG-970/U. This is a right-angle adapter that connects to J104 and converts to a female 
SO-239 standard coax connector. There is a slight mismatch when converting 
from a 125 ohms balanced to 50 ohms unbalanced input but 99% of the time the 
difference will not be noticed. 73 Todd Roberts WD4NGG.
