[R-390] Balanced Antenna Input

[DJED1 at aol.com]

The balanced input will work with any balanced antenna and feed line.   I've 
used it with a balanced loop for MF work, but have not used it with a  dipole. 
 I've also seen balanced 100 ohm cable for sale- I think it may be  used with 
Ethernet networks which used the twinax connectors.  The main  problem, IMO, 
has been the lack of balanced antenna tuners.  However, they  seem to have 
become a hot item again, and at least MFJ sells several balanced  tuners for 
amateur applications.  Maybe I ought to give it a try and see if  it reduces my 
local noise level.
A BNC will work if you isolate it from ground, but the twinax connectors  are 
pretty cheap, so I would recommend those.
