Supports fixed station radio in the 400MHz band. A screen-equipped 3-element Yagi antenna that can be used at a specified frequency.
The S-3DV-450 (S3DV450) is a 400MHz band screen-equipped 3-element Yagi antenna manufactured by Nippon Antenna. It is an antenna for fixed station radios and can be used with vertical or horizontal polarization in a single direction. The operating frequency is a specified frequency within the 330-470MHz band. Please specify the center frequency (fo/MHz). The model number varies depending on the operating frequency. - 340-390MHz: S-3DV-450 F=340-390 - 390-480MHz: S-3DV-450 F=390-480 The structure features a reflector in a screen shape for the Yagi antenna. This enhances the F/B ratio characteristics and efficiently cuts interference waves coming from the rear. It is a 3-element Yagi antenna with a dipole ratio of 6dB and an absolute gain of 8.15dB. The connector is equipped with an N-J type connector. Please use a separately sold coaxial cable for connection to the radio. The connector on the radio side is also sold separately, so please choose according to the radio you are using. *For more details, please feel free to contact us.
