------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ Antenna format: 144MHz: [with add-on radial] 1/2λ 144MHz: [without add-on radial] 1/4λ 430MHz: 1/2λ Frequency: 144MHz~146MHz/430MHz~440MHz Air band/150/300/420/450/800/900MHz reception possible Use: Handy Input impedance: 50Ω Input resistance: 10W Connection: SMAP Total length: approx. 404mm antenna part (including radial ring) Weight: Approx. 70g Antenna part (including radial ring) Add-on radial length: approx. 510mm (excluding threaded part)
