Mounting the 26 GHz or 39 GHz BRU
Mount the BRU on a support pole (2 to 4.5 in or 50 to 114 mm in diameter). The only tool
required to mount the BRU is a 17mm wrench. An Installation Kit is provided with the unit.
One or more BRUs may be mounted on the same pole.
Use the following procedure to mounting the BRU on the pole:
1.
Refer to Figure Error! No text of specified style in document.-1 and use the
instructions supplied with the Pole Mounting Kit to assemble the pole mount
prior to installing it on pole.
2.
Orient the mounting plate so that it is at the appropriate height and 90 degrees
from the pointing direction of the BRU (so the BRU points in the correct
direction when mounted) and secure it (do not over tighten). When using the
M10 nuts, start the nut and screw it down close to its final position. Then place a
drop of anti-seize compound on each bolt, making sure to cover the thread near
the final nut position when the nut is tightened.

Install the BRU onto the Mounting Plate as follows (see Figure Error! No text
of specified style in document.-2):
a)
Insert the two studs with the o-ring, flat washer, lock washer and hex nut
through the clearance holes on the mounting plate.
b)
Slide the BRU to the left until the Rotation Pin on the BRU/BRU Mounting
Bracket assembly aligns with the Pilot Hole of the Mounting Plate and the
two studs are in the elevation adjustment slots.
c)
Push the BRU/BRU Mounting Bracket assembly flush against the mounting
plate so that the Rotation Pin is in the Pilot Hole. Loosely tighten the nuts
on the two bolts, as shown in Figure Error! No text of specified style in
document.-2 and
d)
Figure Error! No text of specified style in document.-3.
e)
Adjust the elevation of the BRU. Tighten the two nuts on the BRU to secure
it at the proper elevation. Attach lightning protection using the grounding
lug on the bottom center of the BRU as appropriate.
The Pole Mount has ±15 degree elevation rotation for the BRU.
