RFI CDX3000-B-Toyota-BHMB-518 CDX-Treme UHF CB Hilux N90 RHS

RFI CDX3000-B-Toyota-BHMB-518 CDX-Treme Compact UHF CB Antenna with Bonnet Hinge Bracket for Toyota Hilux N90 2026+ RHS

The CDX3000-B-Toyota-BHMB-518 is a complete UHF CB antenna and mounting bracket kit combining the RFI CDX-Treme compact collinear antenna with the BHMB-518 bonnet hinge mounting bracket. Designed for the Toyota Hilux N90 (2026+) right-hand side bonnet hinge, it operates on 477MHz with a 0.6m overall length, 10W power rating, and 5m RG58 coaxial cable terminated with an FME female connector.

Product overview

The RFI CDX-Treme is a compact ground-independent collinear UHF CB antenna operating at 477MHz, designed for vehicle installations where a full-length antenna is not practical. The 0.6m overall length and spring base mount provide a lower profile than standard UHF CB antennas while maintaining omni-directional coverage and vertical polarisation for reliable communications performance.

The BHMB-518 bonnet hinge mounting bracket is Australian made from 4mm mild steel with a matte black finish, designed specifically for the Toyota Hilux N90 (2026+) right-hand bonnet hinge position. In Australian vehicles, the right-hand side is the driver side. The bracket provides a secure, vehicle-specific mounting point without requiring drilling or permanent modification to the vehicle body.

The antenna connects via a 5m RG58 low loss coaxial cable terminated with an FME female connector. A UHF male adaptor is also included for direct connection to radios with a UHF female input. The black antenna whip and spring feature a subtle blue band at the base, a detail specific to RFI's CDX-Treme range.

Features and benefits

RFI CDX-Treme compact collinear at 477MHz: The CDX-Treme operates on the 477MHz UHF CB frequency band with a compact 0.6m overall length, providing a lower-profile alternative to full-length UHF CB antennas for vehicles where height clearance or aesthetics are a consideration.

Ground-independent design: The CDX-Treme is a ground-independent antenna and does not require a ground plane for correct operation, making it suitable for bonnet hinge and other body-mounted positions where a ground plane is not available.

BHMB-518 vehicle-specific bonnet hinge bracket for Toyota Hilux N90 2026+: The BHMB-518 is Australian made from 4mm mild steel with a matte black finish, engineered specifically for the right-hand bonnet hinge of the Toyota Hilux N90 (2026+) for a secure, vehicle-specific fit without drilling.

Right-hand side fitment: The BHMB-518 bracket in this kit suits the right-hand side bonnet hinge of the Toyota Hilux N90 (2026+). In Australia, the right-hand side is the driver side. In the USA, the right-hand side is the passenger side.

5m RG58 low loss coaxial cable: The 5m cable length provides sufficient reach from the bonnet hinge mounting position to the radio inside the vehicle cabin, with low loss construction to maintain signal quality across the cable run.

FME female connector with UHF male adaptor: The cable terminates in an FME female connector, with a UHF male adaptor also included for direct connection to radios with a UHF female input, covering both FME and UHF radio connector configurations.

Bottom fix spring base: The bottom fix spring base with large nut and star washer provides a secure antenna mounting point on the bracket, with the spring allowing the antenna to deflect on impact and return to position.

Omni-directional coverage with vertical polarisation: Omni-directional horizontal beamwidth ensures consistent UHF CB signal coverage regardless of vehicle orientation, with vertical polarisation matching standard UHF CB base station antenna configurations.

Australian made bracket: The BHMB-518 bracket is manufactured in Australia from 4mm mild steel, confirming local engineering and quality construction suited to Australian conditions.

Frequently asked questions

Which side of the Toyota Hilux N90 does this bracket suit?
The BHMB-518 bracket in this kit suits the right-hand side bonnet hinge of the Toyota Hilux N90 (2026+). In Australia, the right-hand side is the driver side. The left-hand side variant is available separately as the CDX3000-B-Toyota-BHMB-517. Contact us to confirm the correct bracket side for your installation preference.

Does the CDX-Treme antenna require a ground plane?
No. The CDX-Treme is a ground-independent antenna and does not require a ground plane for correct operation, making it suitable for bonnet hinge mounting positions where a ground plane is not available.

What connector does my UHF CB radio need to connect to this antenna?
The antenna cable terminates in an FME female connector. A UHF male adaptor is also included in the kit for radios with a UHF female input. Contact us if your radio uses a different connector type before purchasing.

Is the BHMB-518 bracket suitable for Toyota Hilux N80 models?
No. The BHMB-518 bracket is confirmed for the Toyota Hilux N90 (2026+) only. For the Toyota Hilux N80 (2015-2025), the correct kits are the CDX3000-B-Toyota-BHMB-515 for LHS or the CDX3000-B-Toyota-BHMB-516 for RHS. Contact us to confirm the correct bracket for your specific Hilux generation.

What is the difference between this kit and the CDX3000-B-Toyota-BHMB-517?
The CDX3000-B-Toyota-BHMB-517 includes the BHMB-517 bracket for the left-hand side (passenger side in Australia) bonnet hinge, while the CDX3000-B-Toyota-BHMB-518 includes the BHMB-518 bracket for the right-hand side (driver side in Australia) bonnet hinge. Both kits suit the Toyota Hilux N90 (2026+) and include the same CDX-Treme antenna. Contact us if you are unsure which side suits your installation preference.
