According to the press release:
The 3000 series eliminates the need to manually aim and lock onto digital signals. Also included are a 12-volt DC power supply and receptacle, and a two-way splitter for a second TV and optional cable input. At only 7.56 inches high by 14.88 inches in diameter, the low-profile RoadStar 3000 offers superior wind resistance while occupying minimal roof space.
Well...It's powerful, has HD and looks nice. I'm sold. How much is it? Don't know yet. Stay tuned (pun intended).
