Hi,
have someone please the schematic for this adapter? I understood that it is almost a decoupling capacitor to separate from the DC component but I could not understand if it includes a 50 ohm terminating resistor or not.
Thanks
Gianni

What manual are you using? All the scanned manuals I know of have the schematic for the CX-1363 as part of the main schematic, along the right-hand side.

For example, this manual from BAMA:
http://bama.edebris.com/download/milita ... 7-5010.pdf

Here are the schematics for the accessories, taken from the main schematic in the above manual:

I have made all of them in mini boxes with BNC connector. This is the only one I actually use to any extent.

Thank you very much! I also am building the small boxes and your schematics and the manual help me a lot.

I had to make some for my URM-25 as well. This is the box I used. Comes in Male-Male, Male Female.
