Big Boost

Providing mobile signal in large open areas, tunnels, mines and lift shafts

How It Works

  1. The complete system is installed on a hill or a high up location This area should be above the area where outdoor coverage is required. A good mobile signal must be available here.
  2. The antenna that points at the mobile networks base station receives the signal and sends it to the StellaHome repeater.
  3. The signal is then sent to the BigBoost which adds powerfull amplification. The bigboost feeds 1 or 2 antennas that point down into the areas that require coverage.
  4. The system is self monitoring and does not require any management.

Frequency: 800/900Mhz


Frequency: 900/1800/2100Mhz


The BigBoost must be used with the stellahome triband.
DO NOT use the BigBoost with any other type of repeater EXCEPT the stellahome triband.

Suitable for..

Quarries, mines, tunnels, elevators, large open areas without signal.

The BigBoost amplifies 900/1800 and 2100Mhz. If you are interested in this system , please contact us

Installation Notes:

The antenna that points towards the operators cell tower must be  pointing roughly 180DEG away from the antenna(2) that point down into the areas that require coverage. This is to reduce feedback between the antennas.

The Bigboost unit and the Stellahome unit as shown in the diagram above MUST be placed in separate waterproof enclosures. DO NOT PLACE THEM IN THE SAME BOX.

The reason for this is feedback and overheating.

Powerfull operator network protection
