RFI CDX-TREME Australian Made Vehicle Heavy-Duty Antenna Rugged 4x4 Offroad

RFI CDX-TREME Antenna Range

Choose an RFI CDX-TREME antenna for your vehicle communications setup. The range includes Cellular and UHF CB options in compact and longer high-gain styles, so you can select an antenna to suit your equipment, vehicle clearance and typical terrain.

Choose an individual antenna or one of the twin packs below. Check that your selected antenna is compatible with your radio or cellular equipment before ordering.

Cellular Antennas

RFI CDX-TREME CDX8194 - 59CM Compact Cellular Antenna

• Frequency bands: 698–960 MHz, 1710–2170 MHz, 2300–2700 MHz and 3400–3800 MHz.
• Nominal gain: 5.5 dBi at 698–960 MHz; 4.5 dBi at 1710–2170 MHz; 5.5 dBi at 2300–2700 MHz; and 6.5 dBi at 3400–3800 MHz.
• Suitable for: Drivers wanting a more compact antenna for everyday vehicle use, or where a lower antenna profile is preferred. Its gain varies across the cellular bands, with 4.5–6.5 dBi nominal gain.

RFI CDX-TREME CDX8197 - 120CM High-Gain Cellular Antenna

• Frequency bands: 698–960 MHz, 1710–2170 MHz, 2300–2700 MHz and 3400–3800 MHz.
• Nominal gain: 7.5 dBi at 698–960 MHz; 4.5 dBi at 1710–2170 MHz; 5.5 dBi at 2300–2700 MHz; and 6.5 dBi at 3400–3800 MHz.
• Suitable for: Drivers who can accommodate the longer antenna and want higher nominal gain in the 698–960 MHz band, often used for lower-frequency cellular coverage. Higher-gain patterns may be more suited to flatter, open terrain than frequent hills and valleys.

UHF CB Antennas

RFI CDX-TREME CDX3000 - 59CM Compact UHF CB Antenna

• Frequency: 476–478 MHz UHF CB band.
• Nominal gain: 3 dBi.
• Suitable for: Drivers who want a compact UHF CB antenna and often travel through hilly or uneven terrain. Lower-gain antennas can be better suited to hilly terrain, though they may have less range across flat terrain.

RFI CDX-TREME CDX5000 - 120CM High-Gain UHF CB Antenna

• Frequency: 476–478 MHz UHF CB band.
• Nominal gain: 5 dBi.
• Suitable for: Drivers wanting a longer UHF CB antenna with medium gain. A medium-gain antennas will be a all-round options for both hilly and flat terrain.

Ruggedised for vehicle use

The CDX-TREME range features RFI’s patented Meander™ PCB technology and a heavy-duty spring design. Cellular models support multiple 4G and 5G frequency bands, while UHF CB models are designed for UHF CB communications.

Antenna gain and length are only part of choosing a suitable setup. Actual performance can also depend on antenna mounting position, vehicle installation, terrain and available cellular or radio coverage. Check the antenna and connector compatibility with your equipment before ordering.
