Reduces performance degradation due to snow. A wideband 12-element Yagi antenna with a snowproof cover, compatible with the 330-470 MHz band.
The 12BD-4502RD (12BD4502RD) is a wideband 12-element Yagi antenna with a snow cover, manufactured by Nippon Antenna, designed for the 400 MHz band. It is a unidirectional antenna for fixed station radios, compatible with a wide frequency range of 330 to 470 MHz. Please specify the transmission frequency ft (MHz) and reception frequency fr (MHz) when placing your order. The structure reduces performance degradation due to snow accumulation on the antenna by covering the radiating elements and the first guiding element of the wideband Yagi antenna with FEP pipes. This is a 12-element Yagi antenna that is a unidirectional type compatible with vertical or horizontal polarization. A Yagi antenna is designed to have directionality towards a specific direction by arranging multiple elements. The 12BD-4502RD is a 12-element type suitable for communication with fixed station radios. The feeding section uses an N-J type connector. Please connect it with a separately sold coaxial cable. The connector on the radio side is also sold separately, so please choose one that matches your radio. This is a made-to-order product. *For more details, please feel free to contact us.
