Description
4400-5000MHz Marine & Vehicle Antenna with Filter
The 4400-5000MHz Filtered Antenna is a high-performance wideband omnidirectional antenna designed for marine, vehicle-mounted and other outdoor RF communication applications. Operating from 4400 to 5000 MHz, the antenna provides reliable broadband coverage with 7±1 dBi gain and 360° horizontal beamwidth.
An integrated RF filter provides effective suppression of unwanted signals outside the operating band. The antenna offers 40 dB out-of-band rejection, while maintaining <1.5 dB insertion loss and <0.5 dB pass-band ripple within the pass band. These filtering characteristics make it suitable for RF systems operating in environments where interference suppression and signal integrity are critical.
With vertical polarization, a 40° ±5° vertical beamwidth and ±1 dB ovality, the antenna provides stable omnidirectional coverage with a controlled vertical radiation pattern. It supports a maximum input power of 200 W, with 50 Ω impedance and VSWR ≤2.0 for reliable RF system integration.
The antenna is built with a high-quality FRP radome for demanding outdoor environments. Its rugged construction supports a rated wind velocity of up to 55 m/s, operational humidity of up to 95%, and an operating temperature range of -40°C to +60°C. IP65 waterproof protection helps protect the antenna against rain and environmental exposure.
With dimensions of Ø32 × 800 mm and a weight of approximately 3.5 kg, the antenna is suitable for fixed outdoor and mobile platform installations. DC grounding provides lightning protection for installations exposed to outdoor conditions.
