400MHz Band 8-Element Yagi Antenna 8DV-450

Single-directional 400MHz band 8-element Yagi antenna composed of an antenna, reflecting elements, and guiding elements.

The 8DV-450 (8DV450) is a 400MHz band 8-element Yagi antenna manufactured by Nippon Antenna. *The Yagi antenna is a type of antenna made up of three rods of different lengths, functioning as a director, driven element, and reflector, which provides high directivity. 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. The model number changes based on the operating frequency. - 340 to 390MHz: 8DV-450 F=340-390 - 390 to 480MHz: 8DV-450 F=390-480 *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-36(G). *For more details, please feel free to contact us.
