I . INTRODUCTION

1. SCOPE

This document specifies the set of internal motor & manual override of Antenna tilt. In Antenna Argus CVVPX310R-BT1, the electrical tilt can have a fixed value, or can be variable, usually adjusted through an accessory such as a rod or bolt with markings. This adjustment can be either manual or remote, in the latter case being known as 'RET' (Remote Electrical Tilt) – usually a small engine connected to the screw stem/regulator that does the job of adjusting the tilt.

2. IMPLEMENTATION PURPOSE The efficiency of a cellular network depends of its correct configuration and adjustment of radiant systems: their transmit and receive antennas. And one of the more important system optimizations task is based on correct adjusting tilts, or the inclination of the antenna in relation to an axis. With the tilt, we direct irradiation further down (or higher), concentrating the energy in the new desired direction. There are two possible types of Tilt (which can be applied together): the electrical Tilt and Mechanical Tilt. The mechanical tilt is very easy to be understood: tilting the antenna, through specific accessories on its bracket, without changing the phase of the input signal, the diagram (and consequently the signal propagation directions) is modified. And for the electrical tilt, the modification of the diagram is obtained by changing the characteristics of signal phase of each element of the antenna.

3. SCOPE OF WORKS

Scope of works consists of Installation, how to adjust electrical tilt Antenna Argus CVVPX310R-BT1 by manually adjust bolt or rod at the antenna

4. TEST ENVIRONTMENT

To successfully install the electrical tilt, we need to adjust rod or bold with L-en Key. The tools will be deliver to site and include in packet on antenna system, it’s can be find on the back of antenna it self.

I I . PROCEDURES

This document is prepared by NSN to provide the detailed description of work during preparation and installing electrical tilt Antenna.

Before Start

Please make sure that the installer is responsible for :

1. Make sure the installation site is secure and accessible for working 2. Calculate the space requirements 3. Measure and calculate safety distances 4. Ensure installation tools are available 5. Unpack and inspect the delivery 6. Check that all of the required installation documentation (approved TSSR) is

available on site

Adjust Electrical Tilt Antenna

Please do adjust electrical tilt antenna before lifting antenna system, the procedure adjust electrical tilt manually asd follow:

1. Chek document TSSR or RF design form respective site, and find the value of electrical till

2. Please see on the buttom of antenna Argus, there are three (3) bold & rod, in different position defining every type of frequencies: GSM, DCS, or 3G.

3. Please using L-en Key or screwdriver to adjust bolt and rod, do adjust the electrical tilt refer to agreed value. Please take a look on the rod to see electrical value. - Adjusting by moving bolt to right will increased (↑) electrical tilt value - Adjusting by moving bolt to left will decreased (↓) electrical tilt value

Example : electrical tilt site Metro Kampus is set “0/0/0” for GSM, DCS, and 3G electrical tilt site Sumodikaran is set “2/2/2” for GSM, DCS, and 3G

4. Please do frist adjusting bolt and rod at GSM part in the Antenna, please set “0(zero)” and do carefully !

5. Repeat the same procedure from no. 1 till 4 for the DCS frequencies and 3G frequencies
