A fixed station antenna with a screen to suppress interference waves from the rear, compatible with the 330 to 470 MHz band, featuring a 3-element Yagi design.
The S-3BD-4502 (S3BD4502) is a 400MHz band wideband 3-element Yagi antenna manufactured by Nippon Antenna. It is an antenna designed for fixed station radios, compatible with a wide frequency range of 330 to 470MHz. Please specify the transmission frequency ft (MHz) and reception frequency fr (MHz) when placing your order. *The Yagi antenna is a highly directional antenna consisting of multiple elements of varying lengths. It is made up of elements such as a director, radiator, and reflector. It was invented in 1926. This antenna adopts a structure where the reflector of the Yagi antenna is shaped like a screen. This enhances the F/B ratio characteristics and efficiently cuts interference waves coming from the rear. It is a single-directional antenna that supports vertical or horizontal polarization. The connector section uses an NJ connector. Please use a separately sold coaxial cable for connection to the radio. *For more details, please feel free to contact us.
