AntennaSearch - Search for Cell Towers, Cell Reception, Hidden Antennas and more. Type in your address, process your request, then click "View Antenna Results" Click the blue antennas on the map and the ones labeled "Clearwire Spectrum Holdings, lii, Llc" are the ones blasting out the 4G signal. I live two miles within four Clearwire antennas, nuts!!! Zip code 78729. Cant wait to get my EVO in a couple weeks!
