Antenna: it's free.
Your local over-the-air broadcasters are spending big bucks to upgrade their systems to send digital TV over-the-air, but it won't cost you a dime. You can probably receive local digital and HDTV broadcasts right now, for free, if you have the right equipment.
Cable: it's easy.
About 80 percent of TV viewers subscribe to cable, and a quick call to your installer is usually enough to get your HDTV hooked up with cable high-def programming, including high-def locals. For the ultimate in convenience, ask about a high-def DVR.
Satellite: it's sophisticated.
Hate cable companies? Out of range of broadcast towers or the cable system? Satellite offers the most-sophisticated HDTV hardware and often includes high-def options that cable companies lack. Local HDTV still requires an antenna, though.
