Lightning rod equipped directional 3-stage collinear antenna 3DA-150
150MHz band lightning rod equipped directional three-stage collinear antenna
The 3DA-150 (3DA150) is a directional three-stage collinear antenna with a lightning rod manufactured by Nippon Antenna, designed for the 150 MHz band. * A collinear antenna is a high-gain antenna used for radio communication, primarily in the VHF to UHF range. * This product features a directional three-stage collinear antenna with a lightning rod. * It is an antenna for fixed station radios in the VHF band. * It operates within the specified frequency range of 140 to 170 MHz. Please specify the center frequency (fo) in MHz when ordering. * It is an antenna type with 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 6.65 dBi. * The antenna length is approximately 5.27 m. * The weight is 33 kg. * The connector on the antenna side is an N-J type. * The antenna side connector is only N-J. It can be converted to other connectors using an extension coaxial cable. * An 80 cm long 8D-2V coaxial cable extends from the antenna. * For more details, please feel free to contact our company.
