Introducing our new CDX-Treme RUGGEDISED CELLULAR Antenna!
Purpose-built for 4x4s, SUVs and UTEs, the new CDX-TREME Ruggedised Cellular Antenna features a significantly larger, heavy-duty spring built to withstand the toughest terrains and offering a true rugged aesthetic. Its reinforced ferrule architecture ensures unmatched durability and stability, even under extreme off-road conditions. This antenna doesn’t just perform — it makes a statement.
At the heart of the CDX-TREME is RFI’s patented Meander™ PCB technology, designed and manufactured here in Australia and proven to provide superior performance in the most remote locations. Housed within an enlarged radome that’s meticulously engineered to deliver exceptional RF performance, mechanical resilience and long-range connectivity across the full spectrum of 4G and 5G — from 5G LTE (3400–3800 MHz) to 4G LTE (698–960 MHz, 1710–2170 MHz, 2300–2700 MHz).
RFI has focused a particular emphasis on bands critical to marginal coverage areas, including key low-frequency bands increasingly used by telecommunications operators, to ensure robust and reliable connectivity across urban, regional and remote locations. You can trust in the 45+ years of performance from RFI Antennas and that pedigree is again presented in this new antenna solution.
Developed by RFI’s world-class antenna engineering team, the CDX-TREME antenna sets a new benchmark in rugged cellular connectivity — combining cutting-edge innovation with uncompromising reliability. Built tough, performs stronger and looks the part — this is Australian engineering at its finest, ready to tackle the outback and beyond.
