2. ANTENNA LINEFeeder Cable Installation

Firstly measure the length of the feeder cable from therequired height where it has to be connected with jumper

cable on the tower to a certain point inside the shelter 5m

from the roxtec by using a measuring tape.

RF clamps are then fixed with the cable tray at adistance symmetrical to the edges of the tray.

For VCT- 1.5m between two RF clamps

For HCT- 0.6 between two RF clamps.

Cut the six RF cables and insulate the cable openings

temporarily.

Assemble the RF connecter on ground and again put

the temporary insulation on all the connector openings.

TECH VIDYA

Give the proper bend VCT to

HCT corner in RF cable.

Lay the RF cable on HCT.

Provide the dummy clamp at

the bend

Give the proper way S-loop in RF

cable and insert it in shelter through

the roxtec (firstly loose the metallic tieover rubber boot of roxtec.

Major the half meter through the

roxtec and leaf a mark on the cable by

marker

Feeder Cable Installation

TECH VIDYA


22/28

Take out all cable from roxtec

Cut the RF cable from mark point by RF cutter and again make

the RF connector on all the cable and again insert all the cable

through roxtec inside the shelterSeal the roxtec properly

Again lay the RF cable properly over RF clamp near the shelter

Make the earthing kit between the shelter and tower


22TECH VIDYA


23/28

23

And crimp the lugs on

EGB properly by

crimping toolWeather proofing

properly wrapped upon

the all earthing kit

Nearly shelter earthing

kit connect with EGB

by 16 sq mm G.C. lugs


TECH VIDYA


24/28

24

Come inside shelter and connect the surge arrestor with all jumper

cable and RF cable .by (30-32) no spanner


TECH VIDYA

When connect the earthing kit with tower body firstly remove

the tower paint by the help of flat file

After connect the c-clamp at the tower body properly by (12-13)no spanner

For six cables use a three c-clamp

So connect two cable earthing kit one c-clamp this process apply

all the cable

Again weather proofing properly wrapped upon the all earthingkit

Surge arrestor G.C. connect with

IGB by lugs and crimp the lugs

by crimping tool

Now go to the tower cut cable tie

and lay the properly with RF

clamp

* Provide the loop and connect the

RF connector with jumper

connector by(30-32) no spannerand provide the PBC tape only

OK Not OK

*Now again comes inside the

shelter and connect the jumper

connector with BTS by (30-32) nospanner


TECH VIDYA


27/28

Finally weather

proofing wrapped all

the RF connector* Do the labeling of antenna

line(on jumper cable near BTSport, on jumper near RF connector,

RF cable near OD jumper

connector, at the band HCT-VCT,

outside the roxtec, on RF cable

inside the shelter, on both of the

end of ID jumper near BTS port)
