Think carefully about towing an antenna / umbilical with your sub. In ROV
applications, much of the available propulsive power of the vehicle is consumed
just pulling the umbilical through the water. A small diameter cable doesn't
sound like much, but 500 feet of it is a different story.
Best electrical connections for this sort of stuff I have used are connectors
