Cellular Antenna
Get the most out of your 4G/5G booster or router


Better coverage starts with a smarter antenna.
The Zetifi Cellular Smart Antenna is engineered to enhance mobile signal strength in diverse environments. Utilising advanced technology, it ensures consistent and reliable connectivity whether you're navigating flat plains or hilly terrains by adapting to the environment and network.


Enhanced booster performance
The Zetifi Cellular Smart Antenna integrates directly with the Nextivity CEL-FI ROAM R41 signal booster and is compatible with a range of cellular gateway devices. It delivers optimal performance on the Telstra network without manual adjustments. Available in three sizes to suit various mounting locations, vehicle types, and machinery, it combines sleek design with durable construction for reliable connectivity on the move.
Optimised for CEL-FI
Enhances the performance of your mobile signal repeater by intelligently selecting the appropriate frequency band.
Wide frequency range
Supports all frequencies from 698 MHz to 3800 MHz, covering major 4G and 5G bands.
Durable construction
Built with a fibreglass whip and steel ferrule housing the intelligent controller, ensuring longevity and resilience.
Easy installation
Comes with a comprehensive installation kit, including coaxial and power cables, for straightforward setup.

The Zetifi Cellular Smart Antenna enhances the performance of CEL-FI mobile signal boosters by intelligently selecting the optimal frequency band for your specific location. This ensures that the booster amplifies the band your device is using, reducing the time the booster spends scanning for available bands and increasing the likelihood of a successful connection.

Equipped with advanced diagnostics, the antenna continuously monitors the health and performance of your communication system. It can detect issues such as disconnected cables or inactive boosters, sending alerts to your smartphone via the Zetifi Smart Antenna app, allowing for prompt corrective action and reliable connectivity.

Optimised for use with CEL-FI ROAM R41 signal boosters, the Zetifi Cellular Smart Antenna enhances the performance of your mobile signal repeater. By intelligently selecting the appropriate frequency bands based on your location, it helps the CEL-FI to spend more time boosting the right band, and less time scanning.
Choosing the right antenna size
Ideal for flat terrains like the far west of NSW and WA. Best mounted on bull bars due to its length. Offers high/low gain switching for optimal performance.
Ideal for flat terrains like the far west of NSW and WA. Best mounted on bull bars due to its length. Offers high/low gain switching for optimal performance.
Designed for vehicles without bull bars, such as SUVs and 4x4s. This medium (4dBi) gain antenna doesn't have high/low switching but delivers reliable performance, especially in areas with challenging reception like the Sturt Highway near Wagga.

Need both UHF and cellular connectivity?
If you're looking to streamline your vehicle's communication setup, consider the Zetifi UHF & Cellular Combo Smart Antenna. This innovative antenna combines UHF CB and 4G/5G cellular signals into a single, sleek unit, reducing hardware clutter and simplifying installation.

Strategic partnerships driving connectivity innovation
Empowering Rural Connectivity
Zetifi's collaboration with Telstra has been instrumental in advancing rural and remote connectivity solutions. In 2022, Telstra co-led Zetifi's $12 million Series A funding round, underscoring a shared commitment to enhancing connectivity for all Australian’s.
Further solidifying this partnership, Zetifi integrated its team within Telstra Labs in Melbourne. This co-location fosters close collaboration on emerging technologies, including AI, IoT, Wi-Fi, and 5G, accelerating the development of innovative connectivity solutions tailored for challenging environments.
Enhancing Mobile Signal Boosting
Zetifi has partnered with Nextivity, the creators of CEL-FI, to optimise mobile signal boosting capabilities. By integrating Zetifi's smart antenna technology with Nextivity's CEL-FI boosters, users experience improved mobile coverage, particularly in areas where standard reception is unreliable.
This synergy ensures that the CEL-FI boosters amplify the most effective frequency bands for a given location, enhancing connectivity for users across Australia's diverse terrains.
