Wiring with no backbone

The average boat's coax cable TV backbone wiring at the best can be now be describe as venerable, and at the worst outmoded technology, yet it still persists. Your boat's coax cable backbone served its original purpose for decades well. It fed antenna and dockside analog cable system signals throughout the boat to all of those glass tube Panasonic TV's with VCR's built into them. But the world has changed. Analog cable TV systems in marinas are disappearing as cable system providers rapidly switch to digital systems requiring interface boxes.

Some new TV's no longer even have a coax connector. What would you use it for in this modern world? Digital audio, HDMI, USB, component video all yes. Jurassic era coax tech, not so much. Adding to this problem is many satellite TV receivers no longer have a coax cable "To TV" connection either. So what are the options? Let's take a look at the current technology.

TV surgery

Old glass tube TV's never die, they just get thrown away. The is a very well loved Searay 48' sedan bridge, and the bad news is that it has an old electron beam gun TV inside of it. The good news is there isn't a VCR built into it. It works okay, but the coax splitter behind all of the gear has crapped out resulting in poor pictures on the other sets in the boat, and the sound quality is less than stereophonic.

The real trick in replacing older entertainment stuff is in not making the new electronics look out of place, and giving it, as much as possible a "factory made" appearance. The devil is all in the details.

Sewell tames the VGA beast

This is the "Beast", the unholy mother of all over sized cables on a boat. Its huge square head defies passing through almost any hole or conduit in the vessel. Did I use the word conduit, and boat in one sentence? My apologies for that oxymoronic faux pas. Anyway, I'm not exactly sure what chart plotter manufacturers were thinking when they adopted VGA technology to feed images to monitors and TV's, but they sure didn't give the cabling end of this technology a whole lot of thought.
