Autobacs BOOST-L900 5dBi 900mm Mobile Network Antenna Cel-Fi
The BOOST-L900 is a 900mm mobile network antenna with 5dBi gain, optimised for N5, N8, and N28 frequency bands and calibrated specifically for use with Cel-Fi signal boosters. Featuring a detachable fibreglass collinear whip, stainless steel spring, and 4.5m LMR240 coax cable with SMA male connector, it is designed to deliver strong signal performance in regional areas where mobile connectivity is weak.
Product overview
The Autobacs BOOST-L900 is a purpose-tuned external vehicle antenna developed for use in conjunction with Cel-Fi signal boosters, particularly the Cel-Fi ROAM R41. Rather than attempting to cover the full GSM frequency range at which performance is difficult to maintain consistently, the BOOST-L900 is optimised for N5, N8, and N28 frequency bands, which are the most relevant for regional Australian mobile coverage.
At 900mm with a 5dBi gain rating, the BOOST-L900 sits between the 600mm BOOST-M600 and the 1000mm BOOST-M1000 in the Autobacs BOOST antenna range, sharing the same 5dBi gain rating as the BOOST-M1000 in a slightly more compact profile. The detachable fibreglass collinear whip at 16mm diameter sits on a stainless steel spring at 25mm diameter. The 4.5m LMR240 coaxial cable terminates in an SMA male connector for direct connection to compatible Cel-Fi repeater units.
Features and benefits
Calibrated for Cel-Fi signal boosters: The BOOST-L900 is specifically tuned to work in conjunction with Cel-Fi signal boosters including the ROAM R41, focusing on the N5, N8, and N28 frequency bands most critical for regional Australian mobile coverage.
5dBi gain at 900mm: Delivers 5dBi of antenna gain in a 900mm profile, providing strong signal capture for Cel-Fi repeater systems in vehicle installations with a slightly more compact footprint than the 1000mm BOOST-M1000.
Optimised for N5, N8, and N28 bands: Focused on the frequency bands most commonly used for regional Australian mobile coverage on Telstra, Optus, and Vodafone networks, where signal boosting provides the greatest benefit to voice and data connectivity.
Detachable fibreglass collinear whip: The 16mm diameter fibreglass whip is detachable for transport or storage, mounted on a 25mm diameter stainless steel spring for flexible, durable vehicle installation.
4.5m LMR240 coax cable with SMA male connector: The 4.5m LMR240 coaxial cable provides sufficient length for routing from an external vehicle mounting point to the repeater unit inside the cabin, terminating in an SMA male connector for direct connection to compatible Cel-Fi repeaters.
Omni-directional coverage: Omni-directional horizontal beamwidth ensures consistent signal capture regardless of vehicle orientation relative to the nearest mobile tower.
Vertical polarisation: Vertical polarisation matches the polarisation of mobile network base station antennas, maximising signal transfer efficiency between the antenna and the network.

Frequently asked questions
What is the difference between the BOOST-L900, the BOOST-M600, and the BOOST-M1000?
The BOOST-L900 is a 900mm antenna with 5dBi gain, sitting between the 600mm BOOST-M600 with 4.1dBi gain and the 1000mm BOOST-M1000 with 5dBi gain. The BOOST-L900 and BOOST-M1000 share the same gain rating, with the BOOST-M1000 offering a slightly longer profile. All three are calibrated for use with the Cel-Fi ROAM R41. Contact us for guidance on which antenna best suits your coverage requirements and vehicle installation.
Is the BOOST-L900 compatible with all Cel-Fi repeaters?
The BOOST-L900 is specifically tuned for use with the Cel-Fi ROAM R41. Compatibility with other Cel-Fi repeater models has not been confirmed in the available source data. Contact us to confirm compatibility with your specific Cel-Fi repeater before purchasing.
What frequency bands does the BOOST-L900 support?
The BOOST-L900 is optimised for N5, N8, and N28 frequency bands, which are the primary bands used for regional Australian mobile coverage on Telstra, Optus, and Vodafone networks.
Is the whip detachable for transport or storage?
Yes. The BOOST-L900 features a detachable collinear fibreglass whip, allowing it to be removed for transport or when passing through low-clearance areas.
Is the BOOST-L900 sold as a standalone antenna or as part of a kit?
The BOOST-L900 is available as a standalone antenna. It is also included in the ROAM41+L900 complete kit alongside the Cel-Fi ROAM R41 repeater. Contact us if you require the complete kit or the standalone antenna for your application.
