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 serving as a director, the radiating element, and the reflector, resulting in a highly directional antenna. It was invented in 1926. *This antenna is for fixed station radios. *The supported 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 type designed for weight reduction is a unique design by Nippon Antenna. *It offers stable workability and electrical performance. *It has a single-directional vertical or horizontal polarization. *The connector comes with an NJ connector. 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.
