[R-390] Balanced Antenna Input Question

[rbethman]

Dick,

This is one of those things that shows up from time to time.  The REAL 
deal is what is the impedance of the signal generator used?  *IF* you 
use an "antenna" matcher attachment that has the same impedance as the 
R-390A was "originally" designed for, then there IS reason for seriously 
working the problem through.

However, as such attachments are pretty much "unobtanium", there is no 
REAL advantage to going through all this.  Almost all the OLD signal 
generators had attachments for 40 and/or 50 ohm output.
