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. ------------------------------------------------------------------------------------------------------------------ Total length: 0.53m Weight: 137g Gain: 2.15dBi (144MHz), 3.8dBi (430MHz) Input resistance: 100W FM (total) Impedance: 50Ω●VSWR:1.5 or less●Connection: M-P Format: 1/4λ (144MHz), 6/8λC-Load non-radial (430MHz) Format: 1/4λ (144MHz), 6/8λC-Load non-radial (430MHz) *Note: The 144MHz band uses the car body as a ground, so please ensure complete continuity between the base and the body.
