Cellular antennas are devices that transmit and receive radio signals for mobile communication. They are essential components of cellular networks, allowing mobile phones and other devices to connect to the internet and make calls. These antennas can be found on cell towers, rooftops, and even on small cells in urban areas to improve coverage. The design of cellular antennas varies based on their purpose and location. Some antennas are large and mounted on towers, while others are smaller and can be installed in more discreet locations. The technology behind these antennas enables them to communicate with multiple devices simultaneously, ensuring efficient network performance.
