Antenna Bearing Tool

There are a many reasons for using this method in preference to using a compass: 1. Antenna bearings are usually referenced to True North and it is a common mistake to apply the correction for a magnetic bearing in the wrong direction, therefore doubling the offset. 2. In many cases steel work or electric power sources affect the compass. 3. The only magnetic compass available may be the one in your Samsung phone. The principle of use is simple: 1. The Icon for the BTS is located on the map at the transmitting site. 2. The Icon for the Land Mark is located on the map at the land mark. 3. The desired antenna bearing [degrees true] is entered via the pop-up keyboard. [Tap the white text to activate the keyboard entry] 4. The two lines on the map show the line to the land mark [RED] and the desired antenna bearing. You can then point the Red line towards the land mark and aim the antenna along the Green line. Alternatively the Offset can be read from the screen and a protractor/theodolite used in place of the phone.
