400MHz Band Wideband 8-Element Yagi Antenna 8BD-4502
400MHz band fixed station radio antenna
The 8BD-4502 (8BD-4502) is a wideband 8-element Yagi antenna manufactured by Nippon Antenna for the 400 MHz band. * The Yagi antenna consists of three rods of different lengths forming a single antenna, with the shorter rod acting as a director, the radiating element, and the reflector, making it a highly directional antenna. It was invented in 1926. * This antenna is for fixed station radios. * The operating frequency range is 330 to 470 MHz. Please specify the transmission frequency ft (MHz) and reception frequency fr (MHz) when placing your order. * It is used for sharing multiple frequencies with a single antenna. * The external matching unit type, designed for weight reduction, is a unique design by Nippon Antenna. * It offers stable workability and electrical performance. * It has a single directional characteristic with vertical or horizontal polarization. * The connector comes with an NJ plug. Please connect it to the radio using a separately sold coaxial cable. The connector on the radio side is sold separately, so please choose one that matches your radio. * For more details, please feel free to contact us.
