A 3-element Yagi antenna that can share two frequencies with a frequency interval of 48 MHz or less within the range of 330 to 470 MHz.
The 3SBD-4502 (3SBD4502) is a wideband 3-element Yagi antenna manufactured by Nippon Antenna for the 400 MHz band. *The Yagi antenna is a type of antenna that consists of three rods of different lengths, functioning as a director, driven element, and reflector, providing high directivity. It was invented in 1926. *This is an antenna for radio equipment. *It is a 3-element Yagi antenna that can share two frequencies within the 330-470 MHz range with a frequency spacing of less than 48 MHz. *When placing an order, please specify ft (transmission frequency, MHz) and fr (reception frequency, MHz). *The connector is NJ. *The compatible mounting brackets for the antenna are C-31(B) and C-19(B). For extremely low-priced sales of earphone microphones, batteries, and more, please leave it to Excelli. *For more details, feel free to contact us.
