What is this connection?

This connection is on the back of my 06 330 above power connection.

If you zoom in, it says "TELEPHONE" at the top, but that's a big plug for telephone. Looks like a cable TV connection at the bottom

Thanks! Was wondering if i could swap out for a plug for something else

my 305 has a coax cable hookup next to my shore power connection, and a section of coax cable. I guess some marinas have or used to have cable TV hook up.

That is an old school twist lock telephone connection and a coax cable TV hookup.
