4.8 Alignment of BTR(s)
The line of sight alignment of the outdoor units is accomplished by
aligning the BTR(s) to an azimuth and elevation that define RF coverage
of that sector. The azimuth and elevation are located in the Engineering
Package.
This alignment procedure can be done using either single or dual BTR
mount configuration.
The following steps identify the procedure for aligning the BTR(s) to the
proper azimuth that is stated in the Engineering Package. The
fundamental aspect of this procedure is to align the BTR(s) using fixed
reference points (i.e. CPE(s) or Landmarks) and their associated
azimuth offset from the required pointing azimuth of the BTR(s). The
required elevation/tilt angle will be set using an inclinometer.
Procedure 6 – Alignment of BTR(s) (Page 1 of 4)
Step
Action
Observation
The alignment tool must first be put together.
Steps 2 through 10 cover the assembly of the
alignment tool.
Attach the long threaded rod (H) into the side of
the top bracket (A). The top bracket is the plate
with the counter-sunk screw holes in the top.
Refer to Figure 12 & 13.
Hold the top bracket so that the threaded rod is
facing to the right and the counter sunk holes are
up. Attach the right side bracket (C) to the top
bracket using two 6/32 X 5/8 allen head screws
making sure the screws are flush with the top
bracket when installed. The right side bracket
should have the slots and the cut-down portion of
the brackets facing away from you when it is
installed onto the top bracket. You will also
notice there is a straight mark engraved on the
outside of the right bracket.
Refer to Figure 12 & 13.
Hold the top bracket so that the threaded rod is
facing to the right. Attach the left side bracket
(B) to the top bracket using two 6/32 X 5/8 allen
head screws. The left side bracket should have
the slots and the cut-down portion of the brackets
facing away from you when it is installed onto
the top bracket. There is no straight mark
engraved on the outside of the left bracket.
Refer to Figure 12 & 13.

Procedure 6 – Alignment of BTR(s) (Page 2 of 4)
Step
Action
Observation
Attach the tilt protractor (E) to the tilt/azimuth
bar (F) with two 8/32 flat head screws. Hold the
tilt/azimuth bar in your right hand so the
engraved straight line is up and to your left.
Place the tilt protractor (E) in your left hand so
the number slots are facing towards the right.
Using the flat head screws, secure the tile
protractor to the end of the tilt/azimuth bar (F).
Refer to Figure 12 & 13.
Slide the tilt/azimuth bar (F) onto the threaded
rod so that the tilt protractor is set flush against
the right bracket (C). Secure the tilt/azimuth bar
(F) with a wingnut and washer so that the 0 on
the tilt protractor (E) is lined up with the
engraved mark on the right bracket (C).
Refer to Figure 12 & 13.
Attach the azimuth protractor/scope platform (D)
to the tilt/azimuth bar (F) with the protractor
pointed to the engraved straight line on the tilt/
azimuth bar (F). Secure the azimuth protractor/
scope platform using the short 1/4-20
thumbscrew, wingnut and washer.
Refer to Figure 12 & 13.
The bottom support bracket (J) will now need to
be attached to the right and left side brackets.
Turn the alignment tool upside down, using the
two small screws secure the support bracket on
the bottom of the right and left side brackets.
Set the BTR attachment bracket so that it is to the
left and the azimuth protractor/scope platform to
the right. Attach the riflescope on the scope
mounts with the eyepiece towards you.
10
Screw the long 1/4-20 thumbscrew into the
threaded hole on the top bracket (A).
The alignment tool is now installed and ready
to be used to align the BTR(s).
Refer to Figure 12 & 13.

Procedure 6 – Alignment of BTR(s) (Page 3 of 4)
Step
12
Action
Locate the "BTR Antenna Alignment Using
Landmark" sheet within the Engineering
Package. Preset the azimuth offset from 0
degrees on the alignment tool by rotating the
scope plate to the left (if the azimuth offset is
negative) or to the right (if the azimuth offset is
positive) by the offset amount for the landmark
that is being used.
Observation
Azimuth is set.
Note: Each increment on the azimuth plate is 1
degree.
Note: Azimuth and tilt of the BTR is set by
using the relative position of one or more
landmarks (two are suggested, since two
landmarks would not have common errors to
the BTR).
Refer to Figure 14.
13
At the roof location, the alignment tool mounts
to the back of the BTR.
14
Slide the alignment tool over the heat sink so that
it fits flush, then tighten the long thumbscrew so
that is secures the alignment tool to the BTR.
15
Adjust the BTR until the landmark point is in the
center of the crosshairs of the scope.
16
Now the Tilt will need to be set.
Refer to Figure 15.
Note: The proper BTR Tilt can be found in the
Engineering Package.
Note: The inclinometer has two scales on the
device. The one on the left shows actual degrees,
and the one on the right shows a percentage used
in calculating distance to target. USE THE
SCALE ON THE LEFT FOR BTR
ALIGNMENT.
17
Place the inclinometer on the heat sink fins on
the back of the BTR.
Take a reading with the inclinometer using the
proper scale.
Note: Do not place your eye up against the
inclinometer. Look at the reading from 4 to 8
inches away from the inclinometers viewing
window.
Note: Line up the RED center indicator with
the BLACK angle identifier in the viewing
window of the inclinometer.
18
Adjust the BTR as needed and snug the bolts on
the BTR tilt adjustment clamps.
19
Recheck the tilt, repeating steps 17 and 18.
20
Tighten the BTR tilt and azimuth adjustment
clamps.

Procedure 6 – Alignment of BTR(s) (Page 4 of 4)
Step
Action
21
Verify the landmark is still in the crosshairs. If it
is not, redo steps 15 and 20.
22
Loosen the azimuth and tilt adjustment on the
alignment tool and rotate the scope to the center
of the second selected CPE in the scope
crosshairs.
23
Tighten the tilt and azimuth adjustment bolts on
the alignment tool.
24
Read the azimuth offset from 0 degrees to the
second landmark (if available). If the measured
azimuth offset matches the Engineering Package
value, the alignment is complete.
Observation
Note: If they are not, then one or the other (or
both) of the landmarks have bad survey data
(either lat/long or building height or both). To
determine the landmark with the bad data, select
a third landmark and follow steps 15 thru 21.
The two landmarks that agree must be considered
as correct, since the odds of having a common
data error at two different landmarks are very
small. At this point, the landmark with bad data
should have its tilt and azimuth offsets measured
(steps 15 thru 21) and the results recorded on the
offset data sheet and advise the RF Engineer of
this. If two of the three selected landmarks do
not agree with predicted offset from the BTR,
then the RF Engineer should be contacted for a
solution. The CPE with measured offsets that are
different from the expected offsets must be
highlighted for link budget corrections for the tilt
and azimuth offsets.
25
Repeat this procedure as necessary for all BTRs.
