I just got a Zenith HDTV Antenna so I'm learning the Google Maps API by finding coordinates for the various HDTV transmitters in the Winston Salem area. Eventually I hope you will be able to enter an address on this page and get some advice about how to point your over the air HD antenna to receive a specific channel and/or the most channels available to your location. Locations are approximate; I had a hard time finding specific locations for antennas but tried to get as close as I could.
