Big Boost

Providing mobile signal in large open areas, tunnels, mines..

How It Works

  1. The Bigboost system should be installed on a high location.  A good mobile signal must be available here.
  2. The Yagi antenna points at the base station, receives the signal and sends it to the StellaHome repeater.
  3. From here, the signal is sent to the BigBoost which adds powerful amplification. The Bigboost sends this high power signal to one or two antennas that can point down into the areas that require coverage.
  4. Typical range from these antennas is ~400m.
  5. The system is self monitoring and does not require any management.

Frequency (MHz): 800/900



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

Suitable for..

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


Installation Notes:

The Yagi antenna that points towards the operators cell tower must be  pointing roughly 180DEG in the opposite direction to 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.

    BigBoost - case study in remote villages

    16th May 2019
    Disaster Risk Reduction Project Location: Villages in Catanduanes Island in Philippines Equipment: BigBoost repeater system   These bigboost systems were installed in remote villages in the Philippines to ensure mobile signal during potential climate disasters. The bigboost is installed high up on the hilltop where it can receive a mobile signal. It amplifies the signal and beams it down [...]

    Case Study: Kola Beach Resort, Kenya

    27th February 2016
    Installing the BigBoost mobile signal repeater system. Location: Kola Beach Resort, Mambrui, Malindi, Kenya. Preconditions: There are 3 local mobile operators in Kenya: Safaricom, Airtel, and Telkom Kenya. The mobile signal from these operators in the Kola Beach Resort was very weak,  if not almost non-existent, and this resulted in poor phone call quality. Technical Computer Area (TCA) contacted [...]
