RFI CD2405 2.4 GHz WiFi Terminal Antenna, 4.5dBi, 2400 to 2500 MHz, N Male

The RFI CD2405 (113-CD2405) is a 2.4 GHz Wi‑Fi terminal antenna designed to improve link quality and coverage for fixed wireless gear such as access points, bridges, telemetry radios and industrial IoT gateways. Its collinear, vertically polarised design concentrates signal energy around the horizon, which helps extend usable range and maintain steadier connections across a site compared with low-gain stub or whip antennas.

It connects via an N‑male fitting and is intended for straightforward outdoor mounting where a neat, low-profile antenna is preferred, including facilities, warehouses, utilities sites and transport infrastructure. Within the CD2400 family there are higher-gain, longer variants that trade a narrower vertical coverage angle for extra reach, making them better suited to flatter terrain or longer point-to-point/point-to-multipoint links.
