    1111=== Directional (large node sector) ===
    12 The directional antennas are comprised of a horizontal array of four [attachment:"RFSpace TSA900 directional.pdf" ultra-wideband antenna elements]. Each element is oriented in the vertical plane and spaced 3 inches (7.63mm) from its neighbor. The frequency range covered by the antennas is 900 MHz - 12 GHz. However, due to limitations in the power amplifiers, USRPs, and other RF front end components, the actual frequency ranges are 2.4 - 6 GHz for transmit (non-contiguous, see RF front end for details) and 900 MHz - 6 GHz for receive.

    2020=== Omni-directional (medium node) ===
    21 The omni-directional antennas are comprised of four vertically oriented [attachment:"MobileMark RM-WHF omni.pdf​" multi-band antennas] in a 6” (15.24 cm) 2x2 square pattern with a 14.25”x14.25” (36.2x36.2 cm) ground plane. The frequency range covered by the antennas is 1.7 - 6 GHz. However, due to limitations in the power amplifiers, USRPs, and other RF front end components, the actual frequency ranges are 2.4 - 6 GHz for transmit (non-contiguous, see RF front end for details) and 1.7 - 6GHz for receive.
