Unknown large cable/wire Id assistance

[Eddieclemons]

This big cable is behind my salon entertainment electronics and has a rca style adapter on the end. Anyone know what it is? Thanks

Could be a SSB HF antenna….

Looks like two (three?) different coax ends?

I didn't have a chance to really look at it. It is a large dia. rolled up cable with that one terminal end in the second picture.

That connector looks like an antenna connector of some kind.

So, the bottom picture is the loose end of the same large diameter coax in the top pic? Is that a cap or terminating resister on it's end?
In the top pic, a union to a smaller coax that goes somewhere else?
In the top picture a another coax, even smaller in diameter with a tiny connect?

Ah, time for some cabinet diving..

 

[Eddieclemons]

Definitely a future exploration, but it's way down the list.

I would guess that somebody tried to use an existing SSB coax for a an other device.
You may find the other end up stairs where an antenna is / was.
