Supports a stable communication environment with a snow-proof structure. Wideband 12-element Yagi antenna compatible with the 330-470 MHz band.
The S-12BD-4502RD (S12BD4502RD) is a 12-element wideband Yagi antenna with a screen, manufactured by Nippon Antenna, designed for the 400MHz band. It is a directional antenna used in conjunction with 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. It can be used with fixed station radios such as the Alinco UHF 351MHz band digital simple radio registered station 3R/3T [DR-DPM80] and the Yaesu (Yaesu Radio/Standard Horizon) 3B/3C/3D digital simple radio licensed station [SRM420U]. The structure adopts a screen shape for the reflector of the Yagi antenna, enhancing the F/B ratio characteristics and efficiently suppressing interference waves coming from the rear. FEP pipes are used for the radiating elements and the first guiding element, providing a snow-resistant structure that reduces performance degradation due to snow accumulation on the antenna. *For more details, please feel free to contact us.
