PA, PAL, SP, SPF
PAX, SPX
NMT 552-01(e)
These Installation Instructions are valid for antennas in the following version :
• Reflector Ø 1.2 m (4 ft)
• Single or Dual polarization
• Pipe mount for installation on pipe Ø 114 mm
• Antenna offset to the left or to the right
• Standard installation on 114 mm pipe with offset to the left
• Safety collar for easy installation
• 2 spindles for fine adjustment of Elevation of ± 15° and Azimuth ± 5°
• Reflector without shroud
• 200 km/h version : With sway bar Ø 27 mm x 1.35 m (mandatory)
It is important to mount the antenna exactly as described in this installation instruction.
The installed antenna shall be inspected once per year by qualified personnel.
RFS disclaims any responsibility for the result of improper or unsafe installation.
This installation instruction has been written for qualified, skilled personnel.
We reserve the right to alter details, especially with respect to technical improvement.

3. Pre-assembly of the mount
For easy operation of the bolted joints, and correct torque tightening, « Anti Seize »
Installation Paste must be applied to all threads of bolts and fine adjustment spindles.
After this, keep the lubricated threads free of dust and dirt! (a Torque Table is attached
for specifications)

5. Azimuth safety collar installation on pipe support
Note that the installation of the antenna should be accomplished by qualified personnels,
and well trained person in fair climatic conditions (In any case, always respect the safety
regulation in effect in the country).
Activities involving the use of pulleys, ropes, carabiners and others accessories to hoist antenna
s
and associated products are inherently dangerous. You are responsible for your own actions and
decisions. The use of hoisting systems must be done by qualified and skilled personnel.
Always use certified and controlled equipments, and be sure to respect the breaking load and the
working load limit of each element (pulleys, ropes, carabiners…).
RFS disclaims any responsibility in case of non repect of these warnings..

13. Final Check
When the installation of the antenna has been completed, it is necessary to make
sure that the installation instructions have been followed in all aspects. It is
especially important to check that all bolted joints have been greased and are torque
tightly locked.
For convenience the fixation of the sway bar on the tower structure must be done after complete
fine Azimuth & Elevation antenna alignment.
