Using this antenna is straightforward. First, connect it to your compatible device according to the device's instructions. Remember, since it doesn't come with a power supply, you'll need to use your own suitable power source. Also, you'll have to attach your own antennas. When using it, keep it away from sources of strong interference to ensure good performance. For maintenance, regularly check for any signs of damage on the antenna body. If you notice any issues, handle it carefully and consider seeking professional help for repairs. Store it in a dry and cool place when not in use to prolong its lifespan.
