Sounds like you're asking about KVH TracVision system. I don't have one but have been on many boats with them. Given they seem to be the exclusive domain of newer, slightly expensive yachts, my hunch is they are still several thousand dollars to aquire.
KVH link below has a dealer locator menu if you hunt a bit.
As someone else said, the 12vdc vs 120vac TV is not the barrier. It's the reception antenna
. As an aside, as part of my total refit
of my 1970 Willard Trawler
, decided to remove all vestiges of audio/visual. Gone are holes and mounts for TV and speakers. We use a largish tablet with downloaded movies or stream if wifi
is available. And use Bluetooth speakers for music
If OP is asking about a traditional TV antenna for local TV reception, I found the Shakespeare marine
disk antenna to be useless. I have used one of the newer household style ones that worked pretty well, though is still sort of ugly. Best solution for us was to just stop watching live TV, but we are not sports fans.
