Receiver Antenna Matching (was: Re: [Milsurplus] R-388)

The 4:1 ratio between 200 and 50 Ohms
would be the same as that of the 300 to
75 Ohm TV baluns.  I would imagine that
loss (if any) due to impedance mismatch
would be miniscule.

Re the antenna input impedance.  The standard
appeared to be 200 Ohms.  On the BC-779 and
their clones, and the RBP-2's, the Class A
rhombic antennas used 4-wire transmission
line to the receiver building, and a heavy
200 Ohm twin lead through the building to
the receiver.
