The R-392 receiver was used with the T-195 transmitter to make up the
AN/GRC-19 system. The set was used either with a whip or a dipole depending
whether the unit was used stationary or mobile. The transmitter antenna
tuner is automatically switched over to match a whip or a coax-fed dipole
(50 ohms) depending on the antenna connector used ("N" connector or binding
post). The BNC antenna connector on the R-392 is connected with a short
length of coax to the T-195 transmitter antenna change over relay.
Whether it's a low-Z antenna (whip) or a 50 ohm coax, it's the same input.
The antenna trimmer in the receiver optimizes the match in either case. The
antenna binding post on the receiver is the same input as the BNC.

I'm wondering if the R-392 mobile rx was designed for a hi-Z antenna
input,
since it would have been used with whips on a Jeep and the like.

If I'm running a big outside antenna thru a 52 Ohm coax into the radio,
wuld I
be better off with some kind of matching xformer?
Tnx es 73, Mike K.
