Quick Overview

Cel-Fi GO G41 Repeater for Telstra, Optus or Vodafone is Multi Carrier Dual Band with 240V AC Power Supply and designed for in-building stationary applications where mobile phone coverage is poor and requires boosting of the mobile phone signal throughout office spaces, homes, factories and carparks.

The Celfi G41 4G booster is 100% legal to use in Australia and creates a useable mobile phone signal in areas where signal has never been before.

Many rural areas do not get 5G coverage, so the G41 repeater is the perfect choice with 4G being the main signal available in these areas. In areas where there is 5G 3800MHz, we recommend using the Cel-Fi G51 dual band repeater in place of the G41, otherwise grab the G41 at a fraction of the cost.

This listing is for the Cel-Fi G41 repeater which comes with power cable and data cable only. All antennas and antenna cabling is sold separately. See our kits or call us for a hassle free quote.

The Cel-Fi GO G41 repeater is a professional 3G and 4G mobile phone repeater which is a step up from the G31 mobile phone repeater and has the option to select Telstra, Optus or Vodafone from the nextivity WAVE app (See below for WAVE app store links). This means that if you change mobile phone network providers then you can just swap it over in the app.

The other advantage of the G41 over the G31 is that it boosts 2 bands simultaneously whereas the G31 is a single band booster. What this means is that you can have 3G and 4G boosting at the same time, or you can have 2 by 4G bands boosting at the same time. 

The G41 also has 100dB system gain and is network safe and approved with ACMA in Australia.

Nextivity CelFi G41 will boost the phone network allowing you to use your phone for voice and data calls in places where phone service was previously not available.

The G41 works on bands 1, 3, 5, 7, 8, 28L & 40 whereas the G31 only works on bands 3, (Telstra 5), (Optus 8) & 28 which means that if you have a phone tower that is broadcasting bands 1, 7 or 40 nearby then your phones will probably select one of those bands over the Cel-Fi G31 boosted bands and you will think that the G31 isn't working. The G41 will solve this issue.

The Cel-Fi GO G41 Smart Signal Repeater is designed to solve cellular coverage problems for voice and data. With support for 5G NR operation in traditional LTE bands, the system supports seamless migration to 5GNR once approved by the network providers. At up to 100 dB of gain, it is the most powerful carrier grade solution available. The GO G41 covers up to 3,000 square metres of indoor space per system which is slightly more than the G31 at 2,500 square metres. The Go G41 is also available from us in kit form with antennas and cables or choose from our extensive list of materials to make up your own kit to suit your needs.
