Directional 6-segment collinear antenna with lightning protection at specified frequencies within 330-470 MHz.
The 6DA-450 is a directional six-stage collinear antenna with a lightning rod manufactured by Nippon Antenna for the 400 MHz band. It is an antenna for fixed station radios. The frequency is a specified frequency within the range of 330-470 MHz (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 is equipped with a lightning rod. This antenna has a cardioid radiation pattern, which means that the shape of the directional diagram resembles a heart (cardioid), with the strongest radiation in the front direction. The gain is 11.15 dBi. The antenna length is approximately 5.77 m. It weighs 35 kg. The antenna side connector is an N-J type. Note that the antenna side connector is only N-J; it can be converted to other connectors using an extension coaxial cable. An 80 cm coaxial 8D-2V cable extends from the antenna. The antenna mounting brackets B-4-1 and B-8-1(C) are compatible. For more details, please feel free to contact us.
