  • The Q-Fit™ removable whip system for fast and simple removal when entering low height areas, car washes or for antenna security.

  • When travelling through different terrain, the removable antenna can be swapped over to a larger or smaller size and gain, ensuring the best performance in all geographic areas

  • The bulbar antenna is connected to the repeater via a 5m RG58 tail with an adapted fitting to connect directly onto the Cel Fi Roam’s input connector. A Small Stick On T-Bar Antenna is then connected to the Cel Fi Go’s output in order to disburse the captured signal

  • The repeater provides enough boost to create a small area of coverage around the vehicle.

  • In order to avoid potential interference between the two antennas, they need to be isolated as far apart as possible. We generally install the Cel Fi Roam under the seat and the output antenna towards the back of the vehicle


Why is it legal?

  • Many mobile service providers do not support personal repeaters on their network. This is due to the interference they can cause when connected to the network, or when they are setup incorrectly

  • The Cel-Fi system is the only personal repeater that is widely approved by carriers in Australia

  • The Cel Fi Roam is different to a standard repeater - it is designed to provide maximum coverage, be network friendly, and is easily installed by the end user. It does by:

    • continuously monitoring power levels of the cell tower it is connected to, and constantly adjusting its output power to suit

    • only amplifying and disbursing a particular carrier’s mobile signal, operating within a set frequency band

    • giving the service provider the ability to shut down the repeater remotely if needed, using a signal from the base station

    • not interfering with the carrier’s network or other users on the network

    • having a unique installation process to eliminate feedback into the mobile network.
