Analog cell phones operate on 824-894mhz and PCS cellular (Digital) operates on 1.85-1.99ghz (1850-1990mhz), thus dual band cell phones. The chances of hitting the tower (50-100 feet away) are probably greater than being shot down by the transmitter. Certainly if you fly in close vacinity of any transmitter antenna (I'm talking a few feet, depending on transmitter power), regardless of frequency, it will cause RF overload and block the signal to the receiver. As far as the TV interference, that person should have contacted the tower installer and had them install a filter on the television. Ham radio can also cause TVI and the offending Ham will install a filter. Doubtful that the cell tower will cause any problem other than be an obstruction in flying, which itself is not good. Cell phones (handheld) operate at two different powers levels, .6watts and 3watts. If cell frequencies are a problem you should ban cell phone use at your flying field also.
