Antenna Recommendations:

       Frequency Specific U.FL Per Module = High Gain = Longer Range

                430-440MHz - 860-870MHz - 902-928MHz - 915MHz

       Wide Band U.FL Antennas = Low Gain = Shorter Range

                400-1000MHz - 300-1000MHz etc

Usage:

       Multi-channel RF communication

       Mesh networking

       Wireless sensor networks

       IoT Jamming Applications

       Remote control system

       Data telemetry
