yes they work as OPar mentioned, if you haven't bought your TV it should be digital or you have to use more power and space with a converter box. I bought a small flat scree TV that runs on 12 volt with a cigarette lighter adapter however if you look on the power boxes on some sets they have 12volt others have 9 or anywhere in between. The ones that have 12 volt on them can be run directly off you battery the others have to use a little more power running through an inverter. I bought a set of rabbit ears not the kind that plug in for extra range as I was worried about consuming more power again. I have to move them around and most of the time I set them on the roof. I get reception when I am close to towns but not everywhere and usually not that many channels but I like remote areas so I expect that and when I get reception it is a bonus.
