1- Purpose of the Document This work instruction document describes the procedures to be followed for the installation of the Antennas and Feeder Cable as employed inthe IRANCELL roect.
The aim is to ensure that the antenna and feeder installation works is performed correctly and in such a manner that avoids the possibility of additional work, meets the measurement specifications and acceptance criteria, facilitates smooth handover to the customer and minimizessubsequent failures. Furthermore, the aim is to ensure that an acceptable high quality of standard installations is consistently achieved in the
customer’s network.
2- Safety & PrecautionsRefer to UltraSite EDGE Antenna System Warnings and Cautions Manual and Installing UltraSite EDGE Antenna System Manual for details.
