400MHz Band 3-Element Yagi Antenna 3DV-450
A single directional 400MHz band 3-element Yagi antenna composed of an antenna, reflecting element, and guiding element.
The 3DV-450 (3DV450) is a 3-element Yagi antenna manufactured by Nippon Antenna, designed for the 400 MHz band. *The Yagi antenna consists of three rods of different lengths that form a single antenna, with the shorter rod serving as the director, the middle rod as the radiator, and the longest rod as the reflector, resulting in a highly directional antenna. It was invented in 1926. *It is primarily a single-directional fixed station radio antenna composed of an antenna, reflector element, and director element. *It operates at a specified frequency within the range of 340 to 480 MHz. The model number changes based on the operating frequency. - 340 to 390 MHz: 3DV-450 F=340-390 City - 390 to 480 MHz: 3DV-450 F=390-480 City *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 brackets for the antenna are C-14 or C-19(D). *For more details, please feel free to contact us.
