This app is showing a azimuth line on map for a given location. In strong electromagnetic field and close to the metal things compasses could not work correct. In those kind of situations this app could be useful to find reference points on map and help to correct align the antenna.
It should be helpful for all the people who: mount sector antennas (f.e. GSM sector antennas), mount any LTE and WIFI client antennas.
All settings are hidden in menu. For further info read help.
If there is any bug, please send me e-mail.
