Business Profile

Minimbah State School is an Independent Public School established in 1997 with a current enrolment of over 800 students.  The school name “Minimbah” means “place of learning” in the local Aboriginal dialect Gubbi Gubbi language.

Business Needs

The administration building had a history of poor mobile coverage which meant that staff and visitors to the main office and reception, the staff room and the sick bay were not always able to connect.

In particular, lack of mobile coverage affected the School’s ability to run their business via their wireless EFTPOS machine in the administration office – payments were not always able to be collected causing problems with parents and staff alike.

Product/s Used

Duncan Campbell from Clan Campbell reviewed the site and decided that the CEL-FI GO for Telstra building pack with Omni Antennas would be the perfect solution to taking the external Telstra mobile signal and disbursing it around the building where it needed a boost.

The GO was chosen over the PRO as the original area needing mobile coverage boosting was a small contained area and did not have the separation distance that the PRO requires to optimise the setup.

Omni antennas were selected as the school was a short distance from a number of Telstra towers.

The CEL-FI GO pack comprised of:

  • CEL-FI GO Stationary for Telstra
  • Blackhawk Omni 698-2700 6dBi
  • Indoor Dome Antennas

CEL-FI GO Stationary model is a one box indoor coverage solution for Telstra’s Next G® and 4GX networks operating on 3G 850Mhz or 4G 700/1800 bands. It is designed to dramatically boost voice quality and increase data speeds for in building applications.

The Cel-fi GO offers a more flexible installation over other CEL-FI models due to the ability to run cables to where the signal is needed most. By not having a wireless link between two boxes (as with the CEL-FI PRO system) GO can operate in areas that are saturated with Wi-Fi.

CEL-FI GO has a gain of up to 100dB ensuring a huge amount of boost internally of the Telstra signal found outside the school buildings.



Not only are staff happy to have a fully operational EFTPOS machine ensuring they can deal with parent payments on the spot, but they also have a solid 5 bars of signal throughout their offices.

The signal amplification extends inside and outside the admin building, with parents and teachers now able to sit in the shade around the building perimeter and use their personal phones with a solid four bars of signal.

This CEL-FI GO installation was undertaken by Duncan Campbell of Clan Campbell Digital Communications whose speciality is improving mobile coverage.  Clan Campbell services the Morton Bay region of QLD and surrounding regional areas and are based in Burpengary.
