Cel-Fi G41 Professional 4G Booster Pack - Wideband Precision Grid Antenna
This is a professional series kit designed for locations requiring the highest performing data connection that the network will permit.
The kit uses a wideband grid antenna that operates across any and all 4G-5G frequencies in Australia with high gain. This system seems most use in challenging RF environments like dense CBD areas or over-subscribed regional areas where achieving a set of clean bands for carrier aggregation is important.
The repeater works for all three networks (Telstra, Optus, and Vodafone), and its high performance antenna makes it suitable for practically any environment. As it's the more expensive of our 4G repeater kits we'd be happy to check whether this kit is right for your location before you buy.
When to use this 4G repeater kit
For urban areas the antenna has been laboratory verified to achieve up to 18.2 dBi on B3 (1800 MHz), 20.5 dBi on B1 (2100 MHz), and 20.8 dBi gain on B7 (2600 MHz). Coupled with its very high Front-to-Back ratio this allows attachment to a specific cell tower, avoiding a more dominant site, or suppressing neighbouring interferers to reduce noise.
In regional areas, due to its large footprint the lower frequencies like 700 MHz can experience high levels of traffic. This kit can be an ideal mechanism to attach to more distant or weaker urban frequencies like B1/B3/B7, and thus avoid the local over-subscribed cell.
We strongly encourage having us check the frequencies and towers available in your local area so that you can maximise performance.
Needs
- Your mobile network is Telstra, Optus, or one of their many resellers (Belong, Aldi Mobile, etc.)
- You've checked the possibility of picking up extra frequency bands in your area
- Booster can be placed inside near a 240V outlet (ordinary household wall socket)
- Professional installation is recommended
5G Compatibility
The Cel-Fi G41 repeater supports 5G on its frequency bands. 5G is rolling out to regional areas on the 850 MHz band for Telstra, 700+900 MHz for Optus and Vodafone. While everything in the kit supports Rural 5G it's up to each mobile network operator to give each frequency the green light. Some bands are already enabled, some are still going through the approval process.
In urban areas the network operators often use a more complex combination of 1800, 2100, and 2600 MHz DSS 5G, many of which are already approved on the G41.
