    20 === Omni-directional (medium node)
     20=== Omni-directional (medium node) without mmWave devices
    2121The 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, [wiki:rf-front-end see RF front end for details]) and 1.7 - 6GHz for receive.

     29=== Omni-directional (medium node) with dual mmWave devices
     30The mmWave version of the medium node antenna housing has the same configuration for the sub-6GHz and GPS antennas as the medium node configuration above. The main difference is in:
     31 * Dual [wiki:/wiki/Hardware/SubSystems/IBM IBM 28GHz Array]
     32 * Fans
     33 * Dual cameras
     34PAAMs are down-tilted X degrees. Covered with Teflon.
