GL490-400 400MHz TNC male Rubber Antenna for IoT terminals

Name: GL490-400 400MHz TNC male Rubber Antenna for IoT terminals
Brand: Global RF Tech
SKU: GL490-400

SKU GL490-400

GL490-400 is a rubber antenna for IoT terminals, gateways, handheld radios and compact RF devices. Its RF data lists 400 MHz operation, 2 dBi gain, liner polarization, and VSWR ＜2.0. Mechanical selection should confirm TNC male connector, 200 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～＋65, 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. Any connector, cable or mounting option not shown on this page should be confirmed before quotation.
