RFI CD2409 2.4 GHz WiFi Terminal Antenna, 8.5dBi, 2400 to 2500 MHz, N Male

The RFI CD2409 is a 2.4 GHz terminal-mounted collinear antenna designed to improve Wi‑Fi link quality by concentrating energy into a flatter, wider “around-the-horizon” coverage pattern. It suits fixed devices such as industrial access points, telemetry gateways and outdoor enclosures where you want better reach and more consistent signal at distance than a small internal antenna can provide, particularly across yards, warehouses, plant rooms or between buildings.

It connects directly via an N‑male interface and is built for outdoor use, so it’s a practical choice for installers and network teams working on site connectivity, monitoring and control networks, and point-to-area coverage. Within the CD2400 series, there are gain options that trade off coverage shape: lower-gain models favour broader vertical coverage for closer-in clients, while higher-gain models like the CD2409 focus more tightly to push range when the client devices are generally on a similar level.
