SAFETY PRECAUTIONS
Read this section carefully before beginning the installation. All of the following requirements should be satisfied
prior to starting installation of your outdoor antennas.
DANGER!
The outdoor antennas to be used with this product are intended for mounting on a roof or on the side of a
building. Any person not trained or experienced in this type of work should not attempt this installation. A suitably
trained professional installation technician must install the antenna. The site prerequisites must be checked by a
person familiar with the National Electrical Code, and with other regulations governing this type of installation.
Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges that may
occur at the antenna (such as a lightning strike during thunderstorms) may damage your electronic equipment
and cause personal injury or death to persons touching the exposed metal connectors of the antenna cable.
When installing, disconnecting or replacing one of the cabling components, you must ensure at all times that each
exposed metal connectors of the antenna cabling system are grounded locally during the work.
Do not install this antenna where there is any possibility of contact with high-voltage arc-over from power cables
or service drops to buildings. The antenna, supporting mast, or tower must not be close to any power lines during
installation or removal, or in the event part of the system should accidentally fail. Apply a Danger label to a plainly
visible area of the antenna support structure.
Do not climb rooftops in wet or windy conditions, during a thunderstorm, or when the area at which the equipment
is to be installed is covered with ice or snow.
Do not touch antennas, surge arrestors, or antenna cables during a thunderstorm.
The antenna installation location must be at a safe distance from power lines or telephone lines. The safe
distance should be at least twice the height of the antenna mast plus the height of the antenna.
Antennas shall be mounted in such a manner as to minimize the potential for human contact during normal
operation. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the
antenna shall not be less than 20 cm (8 inches) during normal operation.
The low-loss antenna cable that is to connect the antenna with the surge arrestor, or with the Ethernet cable that
is to connect to the surge arrestor, must be at least 1 m (3 ft) away from any high voltage or high current cable.
Check whether the antenna mast and its guy wires or wall bracket are positioned correctly and secured properly
to the roof or walls.
Check whether the grounding system for the antenna mast, the MP.11a and 5054-R hardware, and the surge
arrestor have been installed. The grounding system must comply with the requirements as described in
“Grounding the Antenna.”
Always consult a qualified electrician if you are in doubt as to whether the antenna mast, the surge arrestor, and
the hardware are properly grounded.
The antenna cable between the antenna and the surge arrestor must be grounded at all times. If the cable is
disconnected at one end for some reason (for example, to replace the surge arrestor), you must ensure that the
exposed metal connector of the cable is grounded locally during the work.
