Using this telescopic antenna is easy. First, find a suitable spot on your device. Use the 5mm bolt and nut to mount the antenna on the base. The flat - sided bolt will keep it from spinning. You can adjust the antenna to the desired length by extending or collapsing the 5 sections. The swivel base lets you point the antenna in any direction for the best signal. When you're done, you can collapse it to save space. As for maintenance, keep it clean and dry. Avoid bending the antenna too forcefully as it may damage the sections. If you notice any issues with the solder tag, have it checked by a professional. With proper care, this antenna will serve you well for a long time.
