GL4503 430-450 MHz Spring FRP Anti-Jamming Antenna

Name: GL4503 430-450 MHz Spring FRP Anti-Jamming Antenna
Brand: Global RF Tech
SKU: GL4503

SKU GL4503

GL4503 is a 430-450MHz Spring FRP Anti-Jamming Antenna for RF systems, IoT devices, gateways and custom wireless projects. Its RF data lists 430-450 MHz MHz operation, vertical polarization, and VSWR ≤2.0. Mechanical selection should confirm N-Male connector, 32 x 720 mm dimensions against the installation plan. The specification table keeps frequency, gain, impedance, connector, cable, mounting and environmental details grouped for this exact model. Operating temperature is listed as -40°c～60°c, which should be checked for outdoor, indoor or vehicle exposure before sampling. Use the related products and technical sheet link to compare nearby models without mixing parameters from another antenna family.
