------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ The frequency is 8 element Yagi antenna with 144/430MHz band (136-174/400-470MHz). Gain: 9.5dBi/11.5dBi Impedance: 50Ω FB ratio: 12dB or more Wind speed: 60 m/s Connection: M-J Compatible mast diameter: Ø30 to Ø60 mm Can be used for VHF/UHF repeaters and radios with a rated power of 100W or less. Yagi antenna constructed from aluminum alloy has better performance than ordinary antenna. The instruction manual includes an installation video, making installation easy. It can be installed in an environment where only the front is open, such as the balcony or rooftop of an apartment, saving space. The long type M-J connector can accommodate coaxial cables of different standards for M-P connectors. Yagi antenna performance is best when the element is perpendicular/horizontal to the ground.
