What is the separation crown used for?
Read more: What is the separation crown used for?The separation ring serves two purposes. The first is to physically separate the transmitting antennas—such as sector antennas—from one another. Antennas emit back radiation, which can lead to interference and signal disruption. Since the strength of the electromagnetic field decreases with the square of the distance, even a small separation significantly reduces the mutual interference between antennas. It is worth checking the device specifications to determine the minimum…
