The ROAM41+T is a complete mobile signal repeater kit combining the Cel-Fi ROAM R41 smart repeater with the CLR8-5G antenna. Compatible with 3G, 4G, and 5G DSS signals, it is the only smart repeater approved by Telstra, Optus, and Vodafone for use in Australia, featuring Nextivity's 4th generation IntelliBoost chip and operator switching via the WAVE app. Backed by a 4-year warranty including a 2-year extended warranty.
The Cel-Fi ROAM R41 is a smart mobile repeater designed to boost weak mobile signals in vehicles and boats across Australian networks. As the only smart repeater approved by Telstra, Optus, and Vodafone for use in Australia, the ROAM R41 complies with carrier requirements and can be used without risk of network interference or carrier restrictions. The 4th generation Nextivity IntelliBoost chip delivers improved performance over previous generation repeaters, providing stronger and more consistent signal amplification across supported frequency bands.
Operator switching via the WAVE app allows the user to select which carrier signal to boost and change the selection at any time, providing flexibility when travelling across areas served by different carriers. The kit supports voice, data, and streaming connectivity improvements, with the boosted signal distributed inside the vehicle or boat cabin through the included Cel-Fi internal antenna.
The kit operates on 12V via a cigarette lighter power supply, requiring no permanent wiring for straightforward installation. The plug-and-play setup allows the repeater to be operational within minutes of installation.
Boosts 3G, 4G, and 5G DSS signals: The ROAM R41 supports 3G, 4G, and 5G DSS signal boosting, providing improved connectivity across the major network technologies used in Australia, including in vehicles and boats.
4th generation IntelliBoost chip: Nextivity's latest proprietary IntelliBoost chip delivers industry-leading signal amplification performance, providing stronger and more consistent boosting than previous generation repeaters.

Operator switching via WAVE app: The WAVE app allows the user to select which carrier signal to boost and change the selection at any time, providing flexibility when moving between areas served by different Australian carriers.
Boosts 1 bar to full signal: Designed to take a single bar of mobile signal and amplify it to full signal strength, delivering a meaningful improvement in call quality, upload speed, and download speed in areas with weak coverage.
Voice, data, and streaming support: Improves call, text, and data streaming performance from locations where the native signal would otherwise be insufficient for reliable connectivity.
Plug-and-play setup: Quick and straightforward installation allows the repeater to be operational within minutes, with no permanent wiring required.
12V cigarette lighter power supply: Operates from a standard 12V cigarette lighter socket, suitable for vehicles, caravans, and boats without requiring a hardwired installation.
Includes Cel-Fi internal antenna: The kit includes a Cel-Fi internal antenna to distribute the boosted signal throughout the vehicle or boat cabin for consistent coverage across connected devices.
4-year warranty including 2-year extension: Backed by a 4-year total warranty, comprising the standard manufacturer warranty plus a 2-year extended warranty included with this kit.

What is the difference between the ROAM41+T and the ROAM41+M600, ROAM41+M1000, and ROAM41+L900 kits?
The ROAM41+T uses the CLR8-5G antenna and features Nextivity's 4th generation IntelliBoost chip with operator switching via the WAVE app, while the ROAM41+M600, ROAM41+M1000, and ROAM41+L900 kits use Autobacs Japan BOOST series antennas tuned for regional Australian frequencies. Contact us for guidance on which kit best suits your specific coverage requirements and location.
Is the Cel-Fi ROAM R41 legal to use on Australian networks?
Yes. The Cel-Fi ROAM R41 is the only smart mobile repeater approved by Telstra, Optus, and Vodafone for use in Australia, confirming full compliance with carrier requirements and Australian telecommunications regulations.
What is the WAVE app and what does operator switching do?
The WAVE app allows the user to select which carrier signal the ROAM R41 boosts and change that selection at any time. This is useful when travelling between areas where different carriers provide the strongest coverage, allowing the repeater to be directed at the most useful signal source for each location.
Does the ROAM41+T work with 5G networks?
Yes. The Cel-Fi ROAM R41 supports 5G DSS signal boosting in addition to 3G and 4G. Note that 5G DSS uses spectrum shared with 4G networks. Contact us for further guidance on 5G DSS coverage compatibility for your specific location and carrier.
Can the ROAM41+T be used in a boat as well as a vehicle?
Yes. The source data confirms the ROAM41+T is suitable for use in both vehicles and boats. The 12V cigarette lighter power supply and plug-and-play setup make it practical for marine as well as automotive applications. Contact us for guidance on installation in your specific vessel or vehicle.
