How it works
The Laser is a super narrow, high gain antenna designed specifically for repeater systems. It has a beamwidth of 10deg and gain of 20dBi.
The Laser is most suited to large, urban centres where there are many cell towers in the vicinity.
One might think that the more cell towers in the vicinity, the better the available signal, but in fact the opposite is the case. The more cell towers, the more noise, and the performance of the repeater will degrade. The Laser antenna solves this problem. It has a beamwidth of about 10 degrees. This laser-like beamwidth can “select out” the desired cell tower, whilst at the same time attenuating all the other (unwanted) cell towers.
