Efficiently cuts interference waves from the rear. A 12-element Yagi antenna for fixed stations, equipped with high F/B ratio characteristics in the 400 MHz band.
The S-12BD-4502 (S12BD4502) is a 400MHz band wideband 12-element Yagi antenna manufactured by Nippon Antenna. It is a unidirectional antenna for fixed station radios, compatible with vertical or horizontal polarization. It supports a wide frequency range of 330 to 470MHz. Please specify the transmission frequency ft (MHz) and reception frequency fr (MHz) when placing your order. This 12-element Yagi antenna adopts a structure with a reflector in a screen shape, enhancing the F/B ratio characteristics and efficiently cutting interference waves coming from the rear of the antenna. Due to its high directivity, it can be used as an antenna for fixed stations to communicate in a specific direction. The feed section uses an N-J type connector. Please use a separately sold coaxial cable for connection to the radio. This product is made to order. *For more details, please feel free to contact us.
