Directional 6-segment collinear antenna with lightning rod at designated frequencies within 330 to 470 MHz.
The 6DA-450 is a directional 6-stage collinear antenna with a lightning rod, manufactured by Nippon Antenna, designed for the 400MHz band. It is an antenna for fixed station radios. The frequency is a specified frequency within the range of 330-470MHz (UHF band). Please specify the center frequency (fo) in MHz when placing your order. It features a stacked dipole antenna on a stainless steel mast, providing high gain and durability. It comes with a lightning rod. This type of antenna has cardioid directivity. *Cardioid directivity refers to a pattern where the shape of the directivity diagram resembles a heart (cardioid), with the strongest signal coming from the front. The gain is 11.15dBi. The antenna length is approximately 5.77m. It weighs 35kg. The antenna side connector is an NJ type. *The antenna side connector is only N-J. It can be converted to other connectors using an extension coaxial cable. There is an 80cm coaxial 8D-2V coming from the antenna. The antenna mounting brackets compatible are B-4-1 and B-8-1(C). *For more details, please feel free to contact us.
