General Installation Instructions For Mounting Antennas - Cisco 4G-ANTM-OM-CM Manual

Cisco Industrial Routers and Industrial Wireless Access Points Antenna Guide
— Signals penetrate three or four concrete and wood block walls without degrading signal strength.
— Signals penetrate five or six walls constructed of drywall or wood without degrading signal strength.
— Signals are likely to reflect off a thick metal wall and not penetrate it at all.
— Signals are likely to reflect off a chain link fence or a wire mesh with spaces of 1 to 1-1/2 in (2.5 to 3.8 cm).

Microwave ovens and 2-GHz cordless phones can cause signal interference because they operate in the same frequency
range as the WiFi radios.

Before installing the antenna according to the installation procedures in the following chapters, you must complete these
steps:
— Remove any plug or connector that is installed in the antenna port.
— Verify the correct antenna port for installation, based on the antenna model you are installing.

See the installation document for your router regarding the correct antenna port location. Antennas must be installed in the
correct antenna port for ease of installation and optimal performance.

Vehicle mounted antennas must be separated by at least 18 in (45 cm) to reduce interference between radios. A greater
separation is preferred.

General Installation Instructions for Mounting Antennas

CAUTION: For outside installations, make sure you do not mount the antenna upside down or block the bottom of the antenna
at the cable exit. The correct mounting position is with the cable pointing down (towards the ground) so that any moisture will
drain through the antenna drain holes. The antenna ships with a yellow mounting instruction label temporarily attached to the
antenna radome.
The following instructions are common to most mast mounted installations. For specific installation instructions for each
antenna, see the antenna data-sheet and the router hardware installation guide.
1. Assemble your new antenna on the ground or a level surface at the installation site.
2. Connect its coaxial cable while you are on the ground and attach the antenna to the mast.
3. Ensure that the mast does not fall as you raise or remove it. Use a durable non-conductive rope secured at each two foot
level as the mast is raised. Have an assistant tend the rope, ready to pull the mast clear of any hazards (such as power lines)
should it begin to fall.
4. Use the mounting bracket provided with the antenna.
5. If the installation will use guy wires:
a. Install guy anchor bolts.
b. Estimate the length of guy wire and cut it before raising the mast.
c. Attach guy wires to a mast using guy rings.
6. Carefully connect the antenna and mast assembly to its mounting bracket and tighten the clamp bolts.
In the case of a a guyed (tall, thin mast) installation, you must have at least one assistant to hold the mast upright while the
guy wires are attached and tightened to the anchor bolts.
7. Attach a "DANGER" label at eye level on the mast.
8. Install ground rods to remove any static electricity buildup and connect a ground wire to the mast and ground rod. Use
ground rods designed for that purpose, not a spare piece of pipe.
