The new 33STV from Raymarine makes the dream of underway satellite TV reception available to small boats everywhere. A high performance 33cm (13 in.) satellite dish is contained in a compact and stylish radome measures only 14? in diameter and 15? tall. The antenna weighs less than 10 pounds making it suitable for both powerboats and sail boats as small as 20 feet in length. 33STV is High Definition (HD) compatible and comes standard with our new Multi-satellite Interface Module (MIM.) The MIM conveniently switches your antenna system across 3 broadcast satellites automatically, providing uninterrupted channel surfing just like a home satellite TV system. The 33STV?s included antenna control unit can connect with up to 6 on board satellite receivers using USB connections. The 33STV also features a convenient NMEA0183 GPS interface, which further enhances the speed and performance of the system.
