Cel-Fi GO G41 Omni House Kit

The Cel-Fi GO G41 House Kit with omni-directional antenna is a complete carrier-approved mobile signal booster designed to improve mobile phone coverage inside homes, offices, sheds and commercial buildings.

Unlike the directional Yagi kit, this package includes a Blackhawk Fatboy omni-directional antenna, making it ideal where mobile signals are available from multiple directions or where simple installation is preferred. Supporting Telstra, Optus and Vodafone (one carrier at a time), the GO G41 delivers up to 100dB system gain, supports 3G, 4G, VoLTE and 5G DSS, and provides coverage of up to 3,000m² depending on installation and available outdoor signal.

Cel-Fi GO4 (G41) represents the latest in 4G cellular repeater technology. Building on the success of the GO2 model, GO4 has a higher output power (+20 dBm), providing the largest coverage area of all GO models.

GO4 operates on more frequency bands and can be easily switched between Telstra, Optus and Vodafone-TPG (one carrier at a time) should you change service provider.

Cel-Fi GO4 is ideal for inbuilding cellular coverage applications for Telstra, Optus and Vodafone. The higher output power means more service antennas can be run from the one repeater, and by popular request, the unit now has an RJ45 Ethernet network interface for remote management.

Expanding on GO2’s dual-band functionality, GO4 supports carrier aggregation with 40 MHz of relay bandwidth.

• 700L/850/900/1800/2100/2600 MHz (700 band not supported on Vodafone)
• 3G, 4G, 5G (DSS), VoLTE, NB-IoT
  
• Carrier Switching using WAVE App between Telstra, Optus or Vodafone – one carrier at a time
• Up to 3000 m2 coverage area
• Two bands simultaneous relay
• Total System Relay Bandwidth – Up to 40 MHz
• Remote Monitoring, Control and Alert Capabilities via WAVE Portal (for approved installers)
• Ethernet Port for connection to internet source for live monitoring

What's the difference between this kit and the Yagi House Kit?

The main difference is the external antenna.

This kit includes an omni-directional antenna, which receives signals from all directions and is best suited to urban, suburban and regional locations where nearby towers surround the property.

The Yagi House Kit uses a high-gain directional antenna designed for rural and fringe reception areas where the nearest tower is a long distance away.

Which mobile networks does it support?

The GO G41 can be configured for Telstra, Optus or Vodafone using the Cel-Fi WAVE App. It boosts one carrier at a time, and you can change carriers if required.

Does it support 5G?

Yes. The GO G41 supports 5G Dynamic Spectrum Sharing (DSS) along with 3G, 4G LTE, VoLTE and NB-IoT on supported Australian networks.

How much area can it cover?

Coverage can be up to 3,000m², depending on the available outdoor signal, building construction, antenna placement and installation quality.

Is an omni antenna better than a Yagi antenna?

Neither is universally better—they're designed for different environments.

An omni antenna is best where mobile towers are relatively close or located in different directions. It is much easier to install because it doesn't require alignment.

A Yagi antenna offers significantly higher gain and is the preferred choice for rural properties and fringe reception areas where the serving tower is far away.

Is the Cel-Fi GO G41 legal in Australia?

Yes. The GO G41 is an ACMA-approved and carrier-authorised mobile signal repeater designed specifically for Australian mobile networks.
