High-capacity onboard Wi-Fi requires an antenna that can support multiple data paths without creating a vulnerable roof profile. The PR-NXD-W provides four independent Wi-Fi 6E elements for true 4×4 MIMO, covering 2.4–2.5 GHz and 4.9–7.2 GHz to support efficient data throughput and backward compatibility with earlier Wi-Fi generations. This supports the capacity needed for passenger access and onboard services.
At only 0.625 inch high, the compact dome helps limit exposure to physical contact and vandalism on passenger-rail vehicles. Its ground-plane-independent design can be installed on metallic or non-metallic surfaces, giving system designers more flexibility when planning onboard Wi-Fi hardware.
The polycarbonate housing, fire-retardant LMR-100FR cables, and NFPA 130 and EN 45545 ratings address passenger-rail fire-safety requirements. When properly stud-mounted, IP69K protection helps keep dust and high-pressure water from reaching internal components, supporting exposed service and routine vehicle cleaning. The PR-NXD-W is purpose-built for passenger-rail Wi-Fi and onboard systems that require four Wi-Fi feeds in a low-profile, rail-compliant antenna.
