Screened 3-element Yagi antenna S-3BD-4502RD
Reduces performance degradation due to snow. A 400MHz band 3-element Yagi antenna for fixed stations that cuts interference waves from the rear.
The S-3BD-4502RD (S3BD4502RD) is a 400MHz band wideband 3-element Yagi antenna (snowproof type) manufactured by Nippon Antenna. It is a unidirectional antenna for fixed station radios, compatible with the 330-470MHz band. Please specify the transmission frequency ft (MHz) and reception frequency fr (MHz) when placing your order. The structure adopts a screen-shaped reflector for the Yagi antenna, enhancing the F/B ratio characteristics and efficiently cutting interference waves coming from the rear. The radiating elements and the first guiding element are covered with FEP pipes, reducing performance degradation due to snow accumulation on the antenna. It is a unidirectional antenna compatible with vertical or horizontal polarization. The feed section uses an N-J type connector. Please use a separately sold coaxial cable for connection with the radio. The connector on the radio side is also sold separately, so please choose according to the radio you are connecting. This product is made to order. *For more details, please feel free to contact us.
