2. Setup and Installation
To install the antenna, ensure your radio or walkie-talkie is powered off. Locate the antenna connector on your device, which should be an SMA female type to match the antenna's SMA male connector. Carefully align the antenna's connector with the device's port and gently screw it clockwise until it is finger-tight. Do not overtighten, as this can damage both the antenna and the device connector.
