A Presentation About Outdoor
Installation

2. INTRODUCTION
Kallol Ghosh2
A cell site is a site where antennas and electronic communications equipment are
placed, usually on a tower or other high place, to create a cell (or adjacent cells)
in a cellular network. Cellular (cell) phones first became widely available in the
United States in the 1990s, but since then their use has increased dramatically.
The widespread use of cell phones has led to cell phone towers being placed in
many communities. These towers, also called base stations, have electronic
equipment and antennas that receive and transmit radio frequency (RF) signals.
According to the RF Plan we have to install the antenna at a proper height on
tower. Installation procedure is different for many others company, but there are
no any complexity regarding that installation. In case of Nokia Siemens Network
they don’t use any loop or bend on RF cable. Reliance don’t use any Jumper
cable for a cell site. In this presentation we have discussed about the installation
procedure and quality point of outdoor equipments.

PROCEDURE TO INSTALL AN ANTENNA
Kallol Ghosh7
First we have to make the connection between antenna port and jumper cable
and connection should be weather proofed, and other end of jumper cable
should be covered by polythene. If we give mechanical tilt then it should be
done at bellow, electrical tilt should be avoided at this condition because, it
should be change by touching the tower body.

8. ANTENNA INSTALLATION :
Kallol Ghosh8
We have to take the antenna up on tower with the help of pulley or rope
Keep the antenna away from tower body by pulling the rope carefully.

9. BTS

According to the RF Plan we have to set the
antenna at proper height with the pole mount by
using the antenna clamps with the appropriate
electrical tilt. Antenn

Now the bending portion of RF cable should be carefully placed by using a dummy
clamp at the junction point between VCT and HCT. Then another earthing kit should
be attached along with RF cable by using the cable ties and then RF cable should be
placed on HCT by using the RF clamp. Earthing kit should be straight to the shelter

31. Kallol Ghosh31
RF Cable should be entered into the roxtec and mark the position of RF Cable
then it should be removed from roxtec and cut the mark point on RF cable and
connect the 7/8”M connector. Now finally we insert the RF cable into the roxtec
and connect it with Surge arrestors in same location according to sector wise.
After that we have to make an s-bend on RF Cable near the roxtec.

32. Surge Arrestors:
Kallol Ghosh32
Position of all the surge arrestors are in same.
Now other end of surge arrestors should be connected with indoor jumper cable and
route it on the indoor cable tray by using the cable ties.
