Coax hook-up in a 2015 Crossroads Zinger 32QB

While installing a Coax A-B switch in my TT this past weekend so I could run my Directv dish cablling through the trailers one inbound coax hook-up, to fix an issue this forum helped me address last week, I discovered an extra outbound coax cable.

I unscrewed the panel in the main TV console. This is the panel where the powered OTA antenna comes in, the trailers inbound Coax comes in and the out to the TV in the rear bedroom goes out. I noticed that the factory installed a splitter on the outbound to the rear bedroom and that there are two outbounds.

I have absolutely no idea where the second outbound terminates. I've searched the coach and inspected all the outside ports.

This is a long shot but does anybody out there have a Zinger in the 32 or similar length category? Do you have two outbound coax feeds? Where do yours terminate?

To recap:
Inbound: 1 coax from the outside of the coax for inbound cable tv
Inbound: 1 coax from the OTA antenna on the top of the coach
Outbound: front panel into the main TV console
Outbound: Rear cable on a splitter, one feed to the rear bedroom
Oubtound: Second cable from splitter goes where????
