Wi-Fi Antenna Glass Mount 2.4Ghz Thread: RP-SMA

Signal Optimization: Wi-Fi Antenna Glass Mount (2.4GHz)

In high-performance vehicle installations, the ECU is often buried deep within the chassis—mounted behind a metal firewall, under a seat, or inside a composite dash structure. These locations act as Faraday cages, severely attenuating the Wi-Fi signal required for wireless tuning and telemetry. The Glass Mount Wi-Fi Antenna (2.4GHz) is the engineered solution to this problem. By relocating the radiating element to the vehicle’s glass surface, this antenna bypasses the metal shielding of the chassis, establishing a clear line-of-sight for the RF signal. Ideally suited for the Nexus R5 and other Wi-Fi enabled Haltech units, this component ensures that your wireless link remains strong, fast, and reliable, even when the car is out on the track or the tuner is standing at a distance.

Engineering for Range and Clarity

This antenna features a high-gain element specifically tuned for the 2.4GHz spectrum. It is equipped with a high-quality 1.5-meter coaxial lead terminated with an RP-SMA connector, allowing it to screw directly into the Nexus ECU’s Wi-Fi port. The mounting system utilizes a specialized adhesive tailored for glass application, ensuring a permanent bond that withstands vibration and temperature extremes. By elevating the antenna and placing it on a dielectric surface (glass), the radiation pattern is improved compared to a stubby antenna buried in a footwell, significantly extending the effective range for data logging downloads and laptop connectivity.

Operational Benefits

• Overcome Shielding: Essential for steel-bodied vehicles or installations where the ECU is enclosed in a metal box or firewall cavity.
• Extended Range: Provides superior signal strength for pit-lane telemetry or paddock tuning compared to the standard stubby antenna.
• Flexible Installation: The 1.5m lead allows the antenna to be positioned on the windscreen, rear window, or side glass for optimal aesthetics and performance.
• Secure Fitment: The RP-SMA connector ensures compatibility with standard Haltech Wi-Fi hardware.

Fitment Guide

Recommended for any build using a Nexus Series ECU where the unit is mounted in a location that blocks RF signals.

• Suits: Nexus R5, Nexus R3, Nexus S3, Nexus S2.
