400MHz Band 12-element Yagi Antenna 12DV-450

12-element Yagi antenna for fixed station radio equipment in the 400 MHz band with single-directionality.

The 12DV-450 (12DV450) is a 12-element Yagi antenna manufactured by Nippon Antenna for the 400MHz band. *The Yagi antenna consists of three rods of different lengths forming a single antenna, with the shorter rod serving as the director, the radiating element, and the reflector, making it a highly directional antenna. It was invented in 1926. *It is a single-directional fixed station radio antenna primarily composed of an antenna, reflector elements, and guiding elements. *It operates at a specified frequency within the range of 340 to 480MHz. Please specify the center frequency (fo/MHz) when placing your order. *The supply section and element blanket are molded with reinforced resin. *Due to its protruding type, it can be mounted with rear support. *The recommended mounting bracket for the antenna is C-37(C). *For more details, please feel free to contact us.
