Installation Guide for 3G Antennas
Section 4 - Installation
4.1. - General guidelines
Each antenna is delivered fully assembled in a single packing carton.
Do not stack more than three
units high
.
The antenna has breather/drain holes at its bottom and should be installed with these holes facing
downwards. Do not install the antenna up side down with connectors at the top. The drain holes will be in
a wrong position and the downtilt will no longer operate. Specific antennas should be requested for
installation with connectors at the top.
The strength of the mounting location and its anchoring (pipe …) must be checked by a competent
structural engineer.
Keep in mind all
safety
rules during installation. Do not stand in front of a working antenna and refer to
the operator of the site for the safe working distance from live antennas. Avoid prolonged exposure to
high levels of E-M radiation; refer to nationally agreed safety limits for exposure. Do not rely on antennas
as climbing aids.
Dispose in an environmentally friendly manner.
4.2. - Unpacking and checks
Check that the delivery packaging is not damaged.
Open the box, unpack the antenna system, lay all components on a clean and protected area. If optional
hardware is to be used, do the same with its packaging.
Check carefully that everything has been taken out before discarding the packaging.
Ensure that all installation hardware has been received. Use parts lists provided here as follows for this
clarification.
Ensure that the antenna has not been damaged in transit; inspect its shroud and connectors.
The antenna is delivered with protective caps on all the connectors.
Do not remove these caps until the
antenna is ready to connect the fitting cables, once antenna has been positioned and fixed.
Look at the label at the back of the antenna to check that it is the correct type that is intended to be
installed. Note the serial number written on this label for future records.
The high IMP performance of the antenna depends a lot on the cleanliness of the coaxial connectors. If
any requires cleaning then this must be done with a good contact cleaner which does not leave traces of
oil or grease. If necessary wipe with clean and soft material, free from grease and loose strands of fibre.
4.3 - Antenna installation
At any step of installation, the torque settings are: 20 Nm for M8
30 Nm for M10
We recommend setting the electrical tilt to the maximum before handling the antenna so the electrical tilt
indicator at the bottom of the antenna will be protected.
Assemble one clamp of each pole bracket to the antenna mounting points, by the M8 screws.
Attach a hauling rope to the antenna at the top clamp level and hoist it into required position.
Take extreme care not to damage the antenna connectors when handling onto the support structure.
Position the antenna, fit the remaining clamps and bolt loosely. Swivel the antenna so that it points
roughly in the desired direction.
Lift and fit a pointing device into position. Point the antenna to the specified pointing direction.
Tighten the M10 nuts evenly and in small steps to lock the antenna into position. Do not over tighten. Use
second nut on each bolt to lock tight and secure.
Make sure that the mounting brackets assemblies are pointing in the same direction to minimise stress on
the antenna. This can be confirmed if the hinge bracket screws are loosened a little, the panel should
move gently and freely to its position without any stress.
The pointing device and the hauling rope can now be removed.
