[R-390] Input impedance of R390A

[Tom Warren]

Has anyone actually measured the input impedance at the balanced feedline
connector of the R390A?  Yes, I know they specify 125 ohms as the working
impedance for the antenna/feedline, but that doesn't mean that the actual
input impedance looking into that port is 125 ohms.  I'm pretty sure they
don't specify a conjugate match (then meaning that the input impedance is
125 ohms).  So the question stands, has anyone measured the input impedance
at a number (even one) frequencies.

Curiosity still gets to this cat!!
