Antenna Installation

1. Assembling2. Installation

1. Assembling

1. Unpack the antenna from the cartoon using knife carefully.

2. Verify it according the RF plan.3. Using D-type 12-13 no spanner assemble it.

2. Installation

1. Connect O/D jumper to the antenna port using 30-32 D-type spanner.

2. Do the weather proofing on Jumper-Antenna connection (only PVC tape).

I

Antenna –jumper connection WP

Connect the antenna 2 clamps on the back side of antenna using 12-13 no D-type spanner.

Then use nylon rope for pulling up the antenna over the tower.Tie the rope with antenna.

Then pull the antenna on the tower by pulling rope through the 6” double bearing pulley.

Now connect the antenna on this pole mount (installed as per RF plan) by the use of 12-13 no D-type spanner.

SATETY BELTS

SHOULD BE USED AT HEIGHTS

Antenna is now installed on the tower along with O/D jumper cable

Antenna Line Installation

1. Routing of O/D jumper

Jumper cable (½” , 50Ω)

II

U-shape loop Circular loop

Route the jumper cable along with tower body Provide cable ties at sufficient distance Provide loop on the jumper cable (U-shape/Circular)

All cable ties are tied in same direction and should have smooth edges

At each loop provide the cable ties.

2. Assembling and installation of RF clamps

6 WAY ,7/8” RF CLAMPWITH FULL THREADED NUTS-BOLTS.

Assembled 6 way clamp

Assemble it by using 12-13 D-type spanner.

3-way RF clamp

6-way RF clams Install RF clamps on HCT and VCT (on the rectangular strips) using 12-13 D-type spanner.

RF clampsOn VCT

NOTE : Distance between 2 clamps should be symmetric.i.e On HCT < 1mtr & on VCT =1 to 1.5mtr

2. Routing of RF cable

Cut the RF cable from the roll/drum as per the desired length using RF cable cutter

Made 6 parts of feeder, 2 for each sector.

RF cable cutterRF cable Drum

Connectrorization procedure at one end of feeder cable:

Using knife remove outer insulation from feeder and then using two 30-32 no D-type spanner and made the connectors on each feeder cable at one end.

Then provide temporary seal on each connector.Using rope and pulley pull up the cables on the tower (Connector ends)Made RF-Jumper connection using D-type 30-32 no. spanners.

Provide the weather proofing on the each connection.

PVC TapeRubber TapeButyle Tape

Weather proofing set contains:

4 layers of tapes are provided on each connection. First PVC, Butyle, Rubber and then PVC again.

Route the cable straightly through the clamps on the VCT

Give proper bend at HCT-VCT connection ( bending radius ≥ 300mm)

Provide a dummy clamp at the bend

On HCT also routing should be straight and tight enough

Weather proofing

Provide S-bend on feeder routing before it enters through roxtec

Shelter

S-bend

Insert all cables through the roxtec inside the roxtecMark on the cable at the same position for all cable by keeping 0.5 mtr extraRemove them all, cut from the mark Make connectorization outside the shelter insert again all the cables inside the shelter

Earthing on FeederIII

Earthing kit

Earthing kit with weather proofing kit

•Strip out the outer insulation by knife

•Wrap the kit using combinational plier

•Using 12-13no spanner connect kit with C-clamp for termination on tower body

•Before termination of c-clamp paint from tower body is removed by flat file.
