I've had great luck with the RCA flat panel ones that can sit on top of the set or placed out the port on deck
. They pull in digital signals great. Perhaps there is something mast
mounted but from what I find I get all the TV I can stand this way. These cost under $40 and you can connect them up instantly. I also use a converter box as well as deck
TV fitting when we are docked and have cable access.
Ordinary analogue antennas work pretty well too. When receiving digital they seem to work better. Over the air TV isn't all that great but for local weather
and news it's fine. For the most part it's more channels of shows you really won't want to watch. Better to invest in a nice NAS storage
unit and carry 500 DVDs. The same NAS can also carry 3000 CD's of music
