Relay your mobile phone service

Does your property or mine site have coverage available on geographic high points, but have no coverage inside buildings?

  • The Cel-Fi GO2 system can be designed to retransmit service down to your location
  • Our field technicians achieve coverage over 500m using a single GO and directional antenna, and over 2km using a second repeater.

Professional installation required – Buildings

  • This is an active radio transmitter that requires the appropriate level of theoretical knowledge to install without causing self-interference, and for it to operate at full strength
  • So while it’s possible to self install, we do not provide the Cel-Fi GO2 in a package or kit form, as every installation will be different.

Professional installation recommended – Vehicles

  • It’s possible to self-install the Cel-Fi GO2 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
  • Cel-Fi GO2 can cause interference to your vehicle electronic systems, so we strongly recommend professional installation to make sure you get the best from this product.

A heads up!

  • The Cel Fi Go2 listed here does not include antennas – you can purchase antennas separately.
