3. Free HDTV
Just because you may not have a multi-thousand-dollar satellite HDTV antenna doesn’t mean you can’t have spectacular onboard TV reception. For around $200 or so you can have a compact, 14- to 21-inch-diameter, flat, saucerlike antenna (Shakespeare, shakespeare-marine.com; Glomex, imtra.com) that can pull in a plentiful supply of HDTV programming from local TV stations. No, you are not going to receive HBO, ESPN, the news networks or other cable/satellite TV programming. But you will get a surprising amount of local and national sports, entertainment, news and more in high definition.
