Satellite coax behind Clairion

[Scomor]

Hello again, in the process of repairing the HDMI cable I found the coax cable from the Sat. connection from the outside to behind the Clairon stereo was not connected to anything. I cannot find anything for it to connect to. As it is there is no way a satellite antenna could possibly work. This is on a 2017 23’FB Flying Cloud. Any help will be gratefully be appreciated.
By the way, I was successful in replacing the end on my HDMI cable, it was a full day using an ohmmeter and mapping out what wire goes where but it came out fine. Thanks for all the help!

correct, it just terminates there. to add satellite you need a receiver/tuner which you would install near the coax termination and then you would use an HDMI cable to link the receiver to the matrix splitter or whatnot.
