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.

Antenna Line Installation – Identifying the Items





Antenna Line Installation - Jumpers

Pre-installed Antenna cables are labeled with tape so they can beeasily matched in the top of the cabinet.

There are 2 models of external jumpers. See table below.

Antenna Line Commissioning

For the sweep test, it’s important to set the

right frequency range in the Test Equipment.For the sweep test, it’s important to set the feeder

characteristics, otherwise the results will not be valid.

The table below shows exactly the frequencyrange to be set in the Test Equipment.

Procedure to Perform the Sweep Test






For each feeder, two tests will be performed (RL and DTF). Both of them must be saved. Below you can find the standard file names to be used.
