I purchase a new "Jack" Digital HD antenna ($79CD). Took me 5-10 minutes to install and I instantly went from 1 good and 2 bad channel reception to 4 very good Digital HD quality channels and 3 so so quality channels. Well worth the money and little effort it took and it works awsome with the factory HD TV that came with the trailer. Did also take care of the local providers signal switch from analog to digital output without the need for an additional special converter, this unit alone did it.
Highly recommended, reception does depend on your location of course.
