  • Full service for up to 20 Optus mobile phones or modems

  • Supported Frequencies - 3G 900 or 2100MHz / 4G 1800 or 2100 or 2600MHz (manual selection)

  • Suitable for Optus, Amaysim, Dodo, iiNet, plus more

  • Currently Australia's only legal mobile phone repeater system.




  • The Cel Fi Go2 Repeater for the Vodafone network is a convenient way to boost and distribute a 3G/4G mobile signal within your vehicle including cars, 4WD & trucks

  • Installing this device in your vehicle can improve the reliability of phone calls, text messages, and increase 3G & 4G services

  • This is a complete repeater system designed to provide coverage within and around the Vehicle. 

  • The wideband spring-based whip antenna is ideal for travelling around the country as it offers 6.5dBi gain across the low band 3G and 4G frequencies

  • The bulbar antenna is connected to the repeater via a 4.5m RG58 tail with an adapted fitting to connect directly onto the Cel Fi Go’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 radius of coverage around the vehicle.

  • It's important to note that this repeater unit is designed to provide 3G or 4G services to mobile devices, it cannot produce both networks concurrently. 


Professional installation recommended for vehicles


  • It is possible to self-install the Cel-Fi GO inside your vehicle, however, you must ensure the internal and external antennas are isolated

  • To achieve the appropriate levels of isolation, it's generally recommended that the external antenna is mounted on your vehicle tray, 4WD lightbar/roofracks, rather than bullbar (i.e. isolated by the metal roof)

  • If installing on a bullbar, it's important that the internal antenna is placed in a position that will have the most metal between the external antenna

  • The Cel-Fi GO can cause interference to your vehicle electronic systems, so we strongly recommend professional installation to make sure you get the best from this product.


Why is it legal?


  • Many mobile service providers do not support personal repeaters on their network because of 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 Go is different to a standard repeater, as it's designed for maximum coverage, is network friendly, and is easily installed by the end user. It does this by:

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

    • 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.


A heads up!


  • Optus's Cel Fi Go2 will not boost the 4G+ regional network.
