1. General
Notes:
oPlease read the complete description before starting the installation. Be sure
that connectors are properly sealed from water if no cables are connected to
them after installation.
oTo minimize the risk of thread seizure, an anti-corrosion oil or grease can be
used on nuts and bolts.
Tools required: Wrench,
width: 13 mm
2. Assembly
Fit the 3 parts together and fasten with screws M8 x 20, washers, and spring
washers (M8 torque: 27 Nm).

3. Wall Mounting
M0153AEA_Inst_CMAX-LHM2 Installation Guide for CMAX-LHM2 Antennas Page 5
3. Wall Mounting
To mount the antenna to a wall (pole mounting see next chapter), proceed as follows:
1. Mark 4 holes onto the wall as shown in the drawing above (diameter of the 4
holes: 10 mm).
2. Drill four holes into the wall and insert appropriate expansion bolts into the
holes.
3. Attach the antenna pedestal.
(Note: Expansion bolt parts have to be provided by the user.)

4. Pole Mounting (115 mm max. pole diameter)
Page 6 M0153AEA_Inst_CMAX-LHM2 Installation Guide for CMAX-LHM2 Antennas
4. Pole Mounting (115 mm max. pole diameter)
Optionally, a pole-mounting kit can be ordered separately from CommScope (ID
7814722). The recommended pole diameter for this mounting kit is 60 - 115 mm.
To mount an antenna to a pole using this kit, proceed as follows:
1. Insert four M8x200(2) bolts and four filled-corner washers (5) into the antenna
mounting bracket (see bolt head for details).
2. Insert the pole mounting bracket into these four bolts and place the washers
& spring washers (4 & 5) and the M8 nuts (3) over each bolt (detailed
illustration).
3. Tighten the four M8 nuts observing the specified torque of 27 Nm.
Note:
This installation method is applicable to the CMAX-LHM2-series antenna (CMAX-
LHM2-30-I53, CMAX-LHM2-3030-I53, CMAX-LHM2-22-I53, CMAX-LHM2-60-I53).

5.3. Azimuth Angle
1. Loosen the three fixing
screws at the top and
bottom side. (Do not
unscrew them completely.)
2.
Adjust your desired angle.
The complete antenna
pedestal can be swivelled to
the left-/right-hand side by
up to 50º when mounted to
a pole. With wall mounting,
this angle
is different for
each
antenna type (see
table below).
3. Tighten the fixing screws.

screws at the left- and right-
hand side. (Do not unscrew
them completely.)
2.
Adjust your desired angle.
The complete antenna
pedestal can be swivelled to
down-tilt angle 0-90º.
Note:
The bracket can be
installed in the opposite
direction to achieve up-tilt
angle).
3. Tighten the fixing screws.

5.5. Outdoor Installation
Note: For outdoor use, the plugs must be removed from the drain hole.
NOTICE: For the top and bottom of the antenna, please observe the arrow
markings on the back. The antenna must be installed with the bottom facing the
ground, otherwise water may seep into the antenna and damage it.
Remove the plugs from the drain holes at the bottom of the antenna with a knife
or a flat screwdriver. The figure below indicates the location of the drain holes,
design and/or size of the antenna may be different.
Note:
CMAX-LHM2-30-I53, CMAX-LHM2-22-I53, and CMAX-LHM2-60-I53 antenna
drainage hole layout is similar to the figure above. The figure above is for
reference only. Verify the exact locations with the actual antenna model you have.
