Just found this Android app to find all Digital TV towers with polarisation and direction finder.
Great for setting up antenna in van parks.
I think this is the only Android app of its kind and looks better than the iPhone app Antenna Mate.
DVB-T Australia available free from the Google Playstore.

Hi Rob
I also dowloaded the app but am a bit disapointed.
It worked fine the first time, showed the nearest tower, my location and the tower on a map. the next time I used it from a different location it defaulted to my original location. I may be a dumb asss when it comes to some things technical, if so do you know where on the app I can change my location.

Hi all
I contacted the developer as to how to fix my problem with the app, and received the folling reply:

Please restart phone and check again. After rebooting it could take a while to get gps fix. Please note - if GPS is working on status bar will be gps icon blinking.
There is another possibility to enter position. It is called geocoder (I don't remember which icon in my app was it). It require internet connection. If you will type your address - It will find your position.

This fixed the problem. I can now agree and recomend this app for finding TV towers around Aus.
I hope this information is helpful to anyone that reads it.
