3. Procedure of Antenna Instalation :•
First we unpack the antenna using ballpin hammer, flat head screw driver and combinational pliers. we can use thse tools for unpacking the wooding packing.
•
After that we use knife for unpacking the cotton packing of antenna.
•
Sector sillection process is done by using the mirror compass before the antenna on tower.
•
In sector 1 mechanical tilt is required so these sector's mechanical tilt arrengement is done at the top of the antenna.
•
Sector 2 and sector 3 dose not required any mechanical tilt arrengement is done at the bottom the antenna.
•
After these when assembling process of the antenna is done. using 30-32 spanner then the jumper connector should be connected at the bottom of the site.
•
Weather process of the jumper connector is also done at the bottem of the site.
•
After the process we can give the hot air blow at the jumper connector weather proof
portion for proper weatherproofing process. •
After that we can roll the jumper cableand tied with antenna.
•
After that process two person is climbe up the towerwith pully and rope. and hang the pully on the tower and also fix it with the help of the another short length rope.
•
Pully is hanged atleast 2.5 meter above the antenna height on tower.
•
Then afterone side of the rope is fixed at the one side of the antenna and another end of the rope is connected at the bottom of the antenna is used for back support.
•
After hanging the antenna we can fix it at the pole mount temporarily using the 16-17 spanner.
•
Then we hang another two antenna at another two different sectorsand fix it temporarily for the mechanical tilt arrengement.
•
Mechanical tilt arrengement process is done by using the tilt meter.
•
One personn can stand at the bottom of the tower and another one can stand at the top of the tower then fix the antenna the azimuth angle using the mirror compass.
•
Then pemanently fix the antenna at the pole mount.

3.Procedure
•
First we measure the legth of the RF cable is required for each sector.
•
After measuring the total length of the RF cablead put the temporary insullationon tape of the both side of the RF cables.
•
One RF connector made at the one side of the RF cable and when we make the RF connector then we also temporarily insulate the RF connector.
•
Before laying the RF cable first mark the RF cable using the coloured tape, for each sector we using Tx and Rx ue use different coloure tape.
•
After this processes one person have to climbe up at the tower to hang the pully on the tower pully on the tower.
•
Pully alaways hanged 2 to 2.5 meter above the installed antenna
•
Then after one side of the antenna is tightened with the first RF clamp.
•
Then we hang another two cables for 2nd sector and 3rd sector as the same process as 1st sector.
•
When we lift the cables then one person should be unroll it with a syncronise form.
•
We have to route and lay the cable properly on the cable tray with the help of RF clamp.
•
Then we have to give the proper bend on RF cable at the corner of HCT and VCT.
•
Then we have to put a dummy RF clamp on the bend of the cable.
•
Then we have to make a 's' loop before the wall fit tray.
•
Measure half meter from the wall fit tray and put a marking.
•
Take out all the cables from wall fit tray and cut at the marked position.
•
Then we have to make a RF connector on it at the out side of tthe shelter.
•
Then we have to re-insert the cable through wall fit tray.
•
Then we have to seal the wall fit tray properly.
•
Connect the RF cables with surge arrestor.
•
After that we have to connect the jumper cable with bts to surge arrestor.
