Perhaps this link to my documentation page might be of use:  https://aafradio.org/docs/ARR-1.html (this then leads to the main pdf manual for the ARR-1/ZB-*)

I just got a ZB-1 homing adapter. It’s complete and looks unhacked, but it has two weird connector plugs on the back where the two connectors that a PL-256 would use.  The plug looks like it would take a coaxial cable directly with no center part of what would be the PL-256. It does look original to the ZB-1.  Thoughts?
