  • Page 32: Mounting The Base Station Radio (Bsr)

    Pole-Mounting the BSR Pole mounting allows the MicroMAX to be easily adjusted in the horizontal (azimuth) and vertical (elevation) planes for antenna alignment. The BSR is mounted using the mounting holes located on the BSR's back panel and the supplied pole-mounting brackets. The pole-mounting bracket is designed to support the BSR on a round pole of 45 mm in diameter.
  • Page 33 To pole mount the MicroMAX BSR: Attach the mounting bracket to the MicroMAX: Align the mounting bracket with the MicroMAX's mounting holes so that the mounting bracket's side with the built-in nut is aligned with the BSR's mounting holes furthest from the MicroMAX's bottom panel, as shown in the figure below.
  • Page 34 605-0000-742_MicroMAX_Hardware_Installation_Rev_G Attach the clamping bracket to the mounting bracket: Slide an M6-spring lock washer onto an M6-hex head screw.

  • Page 37: Wall-Mounting The Bsr (Optional)

    Note: A minimum of 3-meter separation is required between mounted MicroMAX's and existing customer radio equipment when transmitting on different sectors (see figure below). However, only a 1-meter separation is required between MicroMAX's when on the same sector and transmitting to the same base station radio without requiring shielding.
  • Page 38 When selecting screw sizes, consideration must be given to the weight of the MicroMAX and load that may be induced in windy conditions.
  • Page 39 Align the mounting bracket's holes with the MicroMAX's mounting holes as displayed below. (The mounting bracket side that provides a groove for inserting a nut must be aligned with the MicroMAX's mounting hole that is nearest to the MicroMAX's bottom panel.) From the external sides, insert the M10-hex head screws through the mounting bracket's holes and MicroMAX's mounting holes.
