[Milsurplus] Early Navy receiver multicoupler

[Nick England]

In case you are curious about such things -
Manual for 1943 vintage 4-output Navy multicoupler CKB-50172 is now on
line - link at
http://www.navy-radio.com/rcvr-coupler.htm
There's also a data sheet on the RXA which had three 10-output multicouplers
Both made by Hoffman

I've seen a similar vintage Signal Corps unit, also using 6AC7's but
with Western Electric instead of Navy coax connectors.

Before these, I guess installations used ?? ohm coax with resistive
decouplers for each receiver? I think that's what I have seen on WW2
battleships?  And maybe open wire with resistive decouplers for some
installations....Rob? Anyone?

cheers,
Nick
