Another thought...
WalMart sells an amplified antenna. You have to plug it into a 110v outlet. It claims to greatly improve the signal. I think it was $30 or so. They had 3 or 4 styles so you could get one that was right for where you wanted to put it.
Not that I saw thereIs there a amp that runs on 12volt?
I don't want to buy a inverter to run it. Is there a amp that runs on 12volt?
I bought an antanna from a truck stop that was supposed to be digital ready,I never got so much as a picture.
never heard of Naxa myself so i can't say weather it will last or not eathier!
