Using this telescopic antenna is easy. First, extend the antenna to your desired length. You can adjust it to 1000mm for maximum reach or collapse it to 275mm when not in use. Then, use the mounting bracket with the single 3mm threaded hole to attach it to your device. Thanks to the swivel base, you can turn it to the best position for signal reception. When it comes to maintenance, keep it clean from dust and debris. You can use a soft cloth to wipe it down. Avoid bending the antenna too forcefully as it may damage the sections. Also, store it in a dry place when not in use to prevent rusting. With proper care, this antenna will serve you well for a long time.
