Bring the world of video on board with marine satellite TV. This is no longer just for big boats. The antenna dome of the Intellian i2 ($2,399, intelliantech.com), for example, measures just 14.7 inches by 15 inches and weighs 9.5 pounds. KVH's M1 ($2,995, kvh.com) dome measures only 13.5 inches by 13.1 inches and weighs only 7.5 pounds. Neither of these offers high-definition TV. If you want HDTV, KVH's HD7 satellite system can bring in HD channels with crystal-clear images, but the retail price starts at $12,995.
