[ARC5] Antenna coupler used with APN-9?

[Mike Everette]

Thanks!  Will see what I can find about it.

 It's a CU-92/APN, Mike.  I have a couple of NIB that have the schematic sheet inside, but I couldn't find them in a quick sweep of the shack.  The boxes make nice housings for a transition from 50 ohm distribution to a push post device in the shack.

  Does anyone know the number of the little antenna coupler box used with the APN-9 LORAN receiver?  I think its purpose was to connect the APN-9 to the same antenna as used by the liaison receiver (BC-348, ARR-15 or ARR-41 perhaps).  It has an SO-239 receptacle and push posts for the antenna (and one of the receivers). 
  What is the circuit of this unit?  Does it match the wire antenna to 50 ohms somehow for the LORAN set? 
  I have one of these with the nomenclature removed, so even though I know what it is, it's still a whatzit... wanted to maybe use it to connect a BC-348 to an antenna using a 50-ohm electronic TR switch, either with the coupler as-is or modified as necessary.  Anyone have an e-mailable diagram and perhaps the specs for the coupler?
