SB, SBX (All Freq. Excepted 142) NMT 560-03(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 an easier installation
• 2 spindles for fine adjustment of Elevation of ± 15° and Azimuth ± 5°
• Reflector with shroud, shroud aperture covered by a rigid radome
• 250 km/h version : With sway bar Ø 33 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.

6. Assembly of the mount (Feed system not shown, if already installed at chapter 4.)
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 attachedfor specifications)

7. Feed system Installation (For feed systems equipped with tuning plate Ø < 120 mm or without)
Refer to Feed Installation Instructions joined.
8. 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 safetyregulation in effect in the country).
Activities involving the use of pulleys, ropes, carabiners and others accessories to hoistantennas and associated products are inherently dangerous. You are responsible for your own actions and decisions. The use of hoisting systems must be done by qualifiedand skilled personnel.
Always use certified and controlled equipments, and be sure to respect the breaking loadand the working load limit of each element (pulleys, ropes, carabiners…).
RFS disclaims any responsibility in case of non repect of these warnings..

16. Final Check
When the installation of the antenna has been completed, it is necessary to makesure that the installation instructions have been followed in all aspects. It isespecially important to check that all bolted joints have been greased and are torquetightly locked.
For convenience the fixation of the sway bar on the tower structure must be done after completefine Azimuth & Elevation antenna alignment.
