Using this telescopic antenna is easy. First, find the mounting hole on your device that matches the 12mm diameter of the antenna. Attach the antenna securely to your AM/FM radio, cassette player, communication equipment, or small portable TV. You can adjust the angle and direction of the antenna using the swivel base to get the best signal. When you're done, simply retract the antenna back into the equipment for easy storage. As for maintenance, keep the antenna clean and dry. Avoid bending it too forcefully as it may damage the sections. If you notice any issues with the signal or the retracting mechanism, check the connections or contact our customer service.
