Antenna Connections - Cisco 4G-ANTM-OM-CM Manual

Cisco Indoor Swivel-mount Dipole Antenna (ANT-4G-DP-IN-TNC)
Antenna installation and replacement should only be performed at one of the following, certified location types:

Utility maintenance and repair depot

Cisco DF facility

Customer premises field depot

Antenna Connections

Before you install or replace antennas, make sure the router is:

Powered off

Disconnected from all power sources

Disconnected from the Field Area Network (FAN)

Removed from a poletop installation
For Optimum Performance
Antennas transmit and receive radio signals which are susceptible to RF obstructions and common sources of interference that
can reduce throughput and range of the device to which they are connected. Follow these guidelines to ensure the best possible
performance:

Install the antenna vertically and mount it with the cables pointing towards the ground.

Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses, building
superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away from these
obstructions.

The density of the materials used in surrounding buildings' construction impacts antenna signal strength. Consider the
following
— Signals penetrate paper and vinyl walls with little change to signal strength.
— Signals penetrate only one or two solid and pre-cast concrete walls without degrading signal strength.
— 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). The fence
acts as a harmonic reflector that blocks the signal.

Microwave ovens and 2-GHz cordless phones can cause signal interference because they operate in the same frequency
range as the device to which your antenna is connected.

For instructions on installing or replacing a Cisco Connected Grid module, see the corresponding installation and
configuration guide for each module.

Before installing the antenna according to the
— 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.
