Telstra Cel-Fi GO4

What is the Cel-Fi GO4?

The Cel-Fi GO series are a type of inline repeater that picks up weak signal from an external antenna and rebroadcasts it at full strength from its service antenna.

Cel-Fi GO4 G41 is the latest mobile booster which is based on the same inline repeater design as the earlier GO models, but now with an even larger coverage area and supporting multiple frequencies for up to twice the data speed.

The unit has an output power of +20 dBm, an increase from +16 dBm with the previous GO models. That’s an incredible 250% increase in output power.

One of the biggest feature releases with this model is carrier-switching, allowing the unit to be changed instantly between Telstra, Optus, and Vodafone networks. This makes GO4 the first ‘unlocked’ repeater of its kind.

Cel-Fi GO G41 is dual band, meaning it can rebroadcast two Telstra channels at a time. This means the unit can be set to boost 3G and 4G simultaneously, or boost two 4G channels to support faster speeds through carrier aggregation.
