      Boosts all Major Networks (+ Virtual Ones)

      This unit can boost available signal for O2, EE, Three, Vodafone & all Mobile Virtual Network Operators - you can find a full list here.

       

      The CEL-FI GO G41 can only boost one main network at a time - if you are wanting to boost more than one network at once then please see the CEL-FI QUATRA 4000e.

       

      Each G41 will amplify the signal of both the main AND all hosted networks, on 3G, 4G and 5G* (*5G subject to coverage) simultaneously. If configured for O2 it will also work for giffgaff, Sky Mobile, Tesco Mobile etc.

      Future Proof - Your Investment is Protected

      Whilst the G41 can only boost one main network at once, unlike other units you don’t need to buy a new unit if you change network in the future.

       

      Simply use the Wave app (which you will need to download during installation) and you can easily change the settings within a few seconds.

      What is this Model Suitable For?

      This model is designed for homes or office buildings that have no signal inside the property but do have a signal outside.

       

      If you have a strong signal in parts of the building but not others then the CEL-FI GO G41 will be more suitable for your needs.

       

      If you only need to boost signal to part of the building then you may consider the CEL-FI CONNECT C41 with external antenna, or CEL-FI CONNECT C41 if you have a good signal by a window.

      Ofcom Legally Compliant

      CEL-FI boosters are compliant with Ofcom’s new licence-exempt requirements (IR2102) and legal to use in the UK.

       

      CEL-FI solutions are also licence-exempt under ComReg requirements for Ireland.

       

      The Specific Absorption Rate (SAR) is comparable to that of a smartphone, making them equally harmless to human health and the environment.

An external donor antenna collects the best mobile signal from outside and transmits it to a mobile signal booster unit. The unit strengthens the signal and rebroadcasts it inside the building via internal donor antennas.What is Included in the Bundle?
