• No, you do not have to subscribe to cable or satellite to get digital/HD broadcasts. Chances are most, if not all, of your local stations are broadcasting in digital, if not HD and can be rec'd using a standard UHF and/or VHF antenna.
• There is no such thing as a digital/HD-specific antenna. The same antennas made a few years ago are still being sold today and work just fine for digital TV. The manufacturers simply stuck stickers on the boxes or re-printed the boxes they use to include "Digital" and/or "HDTV".
• When analog broadcasts cease (scheduled for Feb 2009), you do not need to get an HDTV. Using your existing analog TV, you just need something to convert the digital signal to what your set can display. Digital-to-analog converter boxes will be produced for this purpose and coupons (limited quantity) will be made available by the US gov't to subsidize the cost of purchasing these.
• Digital cable or satellite is not the same as digital (OTA) broadcasting. The change-over date will not affect you (unless your provider wants to force you into a potentially higher cost tier of service).

• Be sure to specify if you're using a standard 4:3 (square) TV or a widescreen or 16:9 format TV as the distance does differ.
• Note that you do NOT have to enter a distance since you're trying to find out what's the proper distance. You can leave # 1 blank, specify the TV type on # 2, and fill in ONE of the fields for # 3. Most people don't know how "wide" their TV is since TVs are advertised based on their diagonal size, not their width.
Most people don't need to worry about a lot of the values it calculates. The last two, Maximum Viewing Distance for NTSC/PAL (720x480 / 720x576) (this is for standard-definition DVDs) and Maximum Viewing Distance to HDTV (Fully resolved 1080i, 1920x1080i), are what you're primarily after.
