ment, remember Safety first
Procedure 1 - Prepare BTR for Installation
Step Action Observation
1There are (2) BTR’s per sector, one is the Pri-
mary and the other is the Redundant BTR.
Mount the antenna’s to the BTR’s before you
install the BTR’s to the mast. The next steps will
cover the procedure of installing the antenna.
Because it is important that you
install the antenna’s right, it should be done in an
controlled environment on stable ground, not
hanging from the mast.

2Both BTR’s must have the same antenna angle.
Verify the antenna angle (15,30,45,60, or 90
degrees) is the proper angle designed for your
site. It is engraved on the side of the antenna.
If the angle does not match the
designed site configuration found in the engi-
neering package, do not proceed with this proce-
dure. Contact the Project Manager.
Note that the above listed angles are the only
configurations supported at this time.
Note: Refer to Figure 1.
3Both the Primary and the Redundant BTR’s will
have the same TX polarity. Verify in the engi-
neering package the TX polarity for each sector.

4.7 Alignment of BTR’s Using the Alignment Tool
The alignment of an LMDS system is accomplished by aligning the
BTR within a sector to an azimuth and elevation that defines RF
coverage of that sector.
This alignment procedure can be done using either BTR mount.
Note: In the event this is an initial installation and there are no CPE
(CTR’s mounted) location. A technician will need to go 2 or more
engineered CPE locations. Once there the technician will need to
validate that there is an antenna mast to mount the CTR to. Then
Figure 17 - Vertical Fine Adjustment Tool Mounted to the Antenna Mast/Dual Mount
31 Loosen the bolts on the back of the BTR’s so that
the Vertical Alignment can be done. In order to
adjust the vertical tilt up or down turn the turn-
buckle in order to do so.
32 The dual mount antenna assembly will now need
to be aligned.

the technician will need to place a white paper plate or balloon on
that mast in order to align the BTR for that sector.
Procedure 4 - Alignment of BTR’s Using the Alignment Tool
Step Action Observation
1The alignment tool must first be put together.
Steps 2 through 9 cover the installation of the
alignment tool.
2Attach 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.
(Figure 15 & 16)
3Hold 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 (2) 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. (Figure 15 & 16)
4Hold the top bracket so that the threaded rod is
facing to the right. Attach the left side bracket
(B) to the top bracket using (2) 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. (Fig-
ure 15 & 16)
5Attach the tilt protractor (E) to the tilt/azimuth
bar (F) with (2) 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). (Figure 15 &
16)
BWA - BTR Microwave Transceiver and RPE Installation / 29
October 12, 1999 Method 08-0283
6Slide the tilt/azimuth bar (F) on to the threaded
rod so that the tilt protractor is sets 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 the the engraved
mark on the right bracket (C). (Figure 15 & 16)
7Attach 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 thumb-
screw, wingnut and washer. (Figure 14 & 15)
8The 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
(2) small screws secure the support bracket on
the bottom of the right and left side brackets.
9Set 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). (Figure 14
& 15)
The alignment tool is now installed and ready
to be used to align the BTR’s.
11 At the roof location the alignment tool mounts to
the back of the BTR.
12 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.
13 Infomation Note: Azimuth and tilt of the BTR is
set by using the relative position of one or more
CPE’s (two are suggested, since two units would
not have common errors if we have bad survey
data) to the BTR.
14 Loosen the BTR’s tilt and azimuth adjustment so
that it can be adjusted for tilt and azimuth set-
tings.
15 Using the Engineering package look at the offset
data sheet for the first CPE. Preset the azimuth
and tilt offset for that CPE (pay attention to the
sign of the offset).

Method 08-0283 October 12, 1999
16 Adjust the BTR until the selected CPE is in the
center of the crosshairs of the scope.
17 Tighten the BTR tilt and azimuth adjustment
clamps.
18 Verify that the CPE is still in the crosshairs. If it
is not redo steps 16 and 17.
19 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.
20 Tighten the tilt and azimuth adjustment bolts on
the alignment tool.
21 Read the azimuth and tile offset to the second
CPE. If the measured tilt and azimuth offset is
the same as predicted (+/- 0.5 degree) for both
CPE’s the setting of the BTR is considered
GOOD.
Note: If they are not, then one or the other
(or both) of the CPE’s have bad survey
data (either lat/long or building height or
both). To determine the CPE with the bad
data, select a third CPE and follow steps
19 thru 21. The two CPE’s that agree
must be considered as correct, since the
odds of having a common data error at
two different CPE’s are very small. At
this point, the CPE with bad data should
have its tilt and azimuth offsets measured
(steps 19 thru 21) and the results recorded
on the offset data sheet and advise the RF
Engineer of this. If two of the three
selected CPE’s do not agree with
predicted offset from the BTR, then the
RF Engineer should be contacted for a
solution. Those CPE with measured
offsets that are different from the
expected offsets must be highlighted for
link budget corrections for the tilt and
azimuth offsets.

22 Note: The alignment tool can also
determine the initial setting of the BTR
tilt or it can check an existing tilt setting
of the BTR. To initially set the BTR tilt,
preset the desired tilt angle using the
offset protractor and adjust the BTR so
that the scope platform is level. The BTR
is now tilted (up or down) the required
amount. To check an existing tilt, move
the scope platform unitl it is level. Read
the existing tilt from the tilt protractor.
23 Repeat this procedure as necessary for all BTR’s.
