Product Usage Instructions
Mounting Preparation
Before mounting the antenna, ensure the mounting surface is prepared with
marked holes for installation.
Attaching RF Cables
Connect the RF cables to the antenna input connectors and torque the 4.3/10
connector to 5-8 Nm using a torque wrench.
Vertical Alignment
Use an inclinometer to verify that the antenna is truly vertical after
installation.
Replacement Guidance
If replacement of the Bottom Mounting Bracket is necessary, follow the
provided guidance strictly to maintain performance and safety standards.
GENERAL INFORMATION
The Metro Cell antenna (Figure 1) is a wide-band, compact antenna.
It is the responsibility of qualified personnel to determine the best method
for securely anchoring the bottom mounting bracket of the antenna to the
mounting surface.
INSTALLATION INSTRUCTIONS
- When unpacking the antenna, do pay attention to port protection before placing the antenna on the ground.
- Examine the antenna and hardware to ensure that all parts are enclosed and that there is no physical damage.
- Verify that the frequency range shown on the label on the bottom of the antenna matches the frequency range of the station equipment.
Notice:
The designed Mounting Interface of CommScope Small Cell models is the centre
25mm diameter hole and surrounding 3pcs 8mm diameter holes on the Bottom
Mounting Bracket. The Center hole serves as the mounting function, surrounding
holes serve as the orientation fixing function.
Instruction Sheet
Notice:
Before mounting the bottom mounting bracket to the mounting surface, position
the antenna unit so that the antenna is oriented as desired. Check Ref0 mark
on bottom endcap for orientation reference. Figure 2 details the position of
Ref0 mark.
- Refer to Figures 2, 3 and 4 for mounting and pattern alignment. It is recommended that the mounting holes be marked and made ready on the mounting surface before installing the antenna.
- Attach the RF cables to the antenna input connectors and torque the 4.3/10 connector to 5-8 Nm (45- 71 LB-IN), refer to Figure 5.
REPLACEMENT GUIDANCE OF BOT MTG BRACKET
Bottom Mounting Bracket Is INHERENTLY one part replacing it i customello need reeplace it. following below guidance and requirement:
- Do NOT replace or discard any other part except the Bottom Mounting Bracket.
- Keep using original M10 fasteners on antenna (they are designed for minimizing PIM impact).
- Customized bracket needs to have 4 mounting points (same as original bracket), mounting area should not be smaller than original bracket.
- Recommended bracket thickness is 6mm, thickness MUST be within range 5 – 7mm, otherwise PIM level may be influenced.
- Apply Loctite 425 to M10 stud and then tighten the M10 fasteners, ensure torque is well controlled with wrench, recommended torque is 30 Nm (266 LB-IN).
SAFETY NOTICE
The installation, maintenance, or removal of an antenna requires qualified, experienced personnel. CommScope installation instructions are written for such installation personnel. Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and condition of equipment.
- CommScope disclaims any liability or responsibility for the results of improper or unsafe installation practices.
