Welcome to Remote Site Technolgies and a brief breakdown about how gain works on a Mobile Phone antenna. If you have any questions, please feel free to give one of our knowledgeable staff a call. 


What is Gain and how does it work in your antenna?

Firstly, bigger is not always better when dealing with Gain of an antenna. If we think of Gain as a balloon, 1bD Gain is mostly a perfect round “signal”. However, when we move to 6dB, the Gain starts to get squashed and once we move up to 9dB, it becomes even more flattened.

So why isn’t bigger better, if it goes a longer distance?

The simple answer is that we don’t live in a flat world. The higher Gain antennas can go a longer distance on flat ground, however, if you were traveling in the hills, the signal on the higher dB antenna would in fact go a shorter distance, due to the hills. This is why we recommend a middle range dB antenna for all of our vehicle kits. However, for a building purpose where you can point an antenna in a fixed direction, we recommend the high Gain antenna, to give the ability to pull a signal down from a further distance.

If you have an application where a truck or 4WD was only traveling on mostly flat land, then moving up to a higher gain antenna would benefit you. Alternatively, if you only operated in hilly areas, a lower gain would be better. However, if you travel in both, then the middle dB solution works best.
