The RDZ is a circa 1944 shipboard receiver covering 225-400 MHz, with
manual tuning or 10-channel autotune, AM only, It is also called the
CNA-46275 unit of RDZ. If I'm not confused, that receiver, paired
with the TDZ transmitter, was used for short range ship-to-ship
communication

You should be able to hear local military airports on the thing, and
all manner of military comms. You may be able to hear some of the UHF
satellites although most of that is now encrypted voice.

I believe that this unit may have some spur leakage and I would check
that out with a spectrum analyzer before connecting up and antenna. You
do NOT want to be dumping spurs into the 225-400 band.
