iTranmsitterLocator is a simple application which displays the terrestrial television transmitters within a 50km radius. Currently only UK locations are supported. The main transmitters show as red pins and the minor transmitters with purple pins. Your location is shown with the familiar blue dot. For a selected transmitter a bearings view can be shown which allows you align your TV aerial with the chosen transmitter. Also available for Android in Android Market.
