6. Feed Installation
Refer to Feed Installation Instructions joined.
7. 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 foryour 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..

15. 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.
