2.3 IF cable connection and routingPls ensure the following in IF cable routing1. The IF cable should be routed from top downwards and should bebound at the time of routing.2. The specifications and cross-sectional area of the cable, and the routeand position for the cabling should be decided beforehand.3. The cable should be arranged neatly without any overlapping orcrossover.4. The IF cable should be curved for waterproof consideration under theODU and before entering the IDU room.5. The bending radius of the IF cable should be larger than 30 cm.6. The IF cable should be bound by using the cable ties for outdoor useevery one meter.7. The cable ties for outdoor use should face the same direction. Thereshould be a slack of 3 mm to 5 mm before cutting the cable ties.

If Cable Routing

2.3.1 IF cable connection near antennaIF connector should be fixed to the ODU firmly and water proofedaccording to the standard(Refer the appendix)

2.3.2 Water proof curveHave to ensure there should be water proof curve at the entrance to thecabinet and near to the ODU.


22/33




2.3.3 Loop near to antenna1. 3-5 m Loop of IF cable should be neatly fixed near to the ODU and afterthe 1st grounding of the IF cable, to make sure the availability of IF cablefor future alterations and alignment.2. Ensure the loop bending diameter should not be less than 0.6 m

2.4 Out door GroundingOut door grounding include ODU grounding and IF cable grounding. Whenyou are grounding any cables, ensure one end of the cable is effectivelyconnected the main grounding bar directly or other routes.Remark: All grounding cables should be down wards.

2.4.1 ODU Grounding

Remark:1. Grounding cable should be fixed tightly at the ODU and it should berouted downwards.2. Other end should be connected to nearest possible grounding point.3. If Grounding point is not there nearly, first remove the anticorrosionpaint and the oxidizing layer on where you want to fix the grounding.5. The grounding cable should not be spiral.6. After the connection, rustproof and waterproof the grounding points.If you are grounding to the Tower Ensure the paint at the grounding pointise removed and after fixation again repainted


23/33




The grounding cable should be neatly routed and tied and fixed to theshortest possible place as below.

Practical scenarios of rounding issues:

2.4.2 IF cable GroundingIF cable should be grounded through out its routing.If the IF cable Length is greater than 60 m IF cable should be grounded in4 points1. Nearest possible from ODU: Before the loop: marked as 12. Before the bending : marked as 23. Mid place in the tower marked as 34. At the entry point : marked as 4


24/33




If the IF cable is less than 60m, then 3 grounding points are enough.1. Near to the ODU2. Before the Bending3. Before the entry point

Remark:When you ground the IF cable pls consider the following issues1. All grounding cables should be downwards.2. Grounding clip is fully tightened with the outer mesh.3. Water proof is made according to the standard way. Refer 3.1 for howto water proof.

2.4.3 Waterproof at the groundingsIF cable connector at the ODU needs properly made waterproof.

Check whether Cable ties at top and bottom of water proof

2.5 Outdoor Labels

2.5.1 IF Cable Label

The labels for IF cables should be bound with the IF cables by using thecable ties for outdoor use.

3.0 Bundling and fixing the cables using Cable TiesCables must be tightly bundled. The bundled cables should be neatlyarranged.For this We have to use three types of cable ties1. Big ,thick and long Black color cable ties: for out door use

a. IF cable fixing through out the tower.b. To protect the both ends of the water proof


26/33




2. White small cable ties: Indoora. To fix the cables (Power cables, Grounding cables) with the rack

holes.3. Black long thin cable ties: Indoor

a. Tight the cables on the ladder

Cable ties for indoor and outdoor:

3.1 Common issues in fixing Cable tiesBundlingThe bundling requirements are as follows:1. Do not bind the power cable with other types of cables.

2. The cables should be bundled neatly.3. Use cable ties of different specifications according to actualcircumstances.4. Do not connect two or more cable ties and use them as one to bundlecables in case the tightness is reduced.5. After the cable ties are fixed, the extra part of the cable ties should betrimmed such that no burrs exist.6. The spacing between the cable ties should be even and should be threeor four times the diameter of the bundle.7 When making turns for bundled cables, ensure that the bending radius isas large as possible so that the cable cores do not break.


27/33




IF routingBlack UV protect tie-wrap should be used, and fixing IF cable by cross

tightens.For the vertical and horizontal cable run, fixing less than 1m intervals bythe tie-wrap. The IF cable must fix not loosened but not strong tightenedand not any deformation to IF cable.

4.0 Appendix

4.1 Waterproofing Outdoor ConnectorsRequired material:


28/33




Step 1: Clean the connector or the grounding clip.Step 2: Uncoil the waterproof insulation tape.Step 3: Stick one end of the tape to the IF cable 2 to 5 cm away from theconnector or the grounding clip. The sticky side should face inwards.

Step 4: Stretch the tape until it is 3/41/2 as wide as its original size.Stretch the tape in this manner when performing the following steps.Step 5: Wrap the cable spirally towards the connector or the groundingclip at a point that is 2 to 5 cm away from the connector or the groundingclip. Make sure that the overlapping area of the adjacent tape layers is 1/2of the stretched width.Step 6: When the tape reaches a point that is 2 to 5 cm away from theconnector or the grounding clip on the other side, reverse the wrappingdirection so that the tape reaches the starting point.Step 7: When the tape reaches the starting point, reverse the wrappingdirection so that the tape reaches the other ending point. That is, there are

three layers of waterproof insulation tape.Step 8: After wrapping, squeeze the tape until it sticks to the cable. Thisensures that there is no air between the layers of tape.Step 9: Similarly, wrap three layers of PVC tape over the waterproofinsulation tape. During the wrapping, maintain the stretched length suchthat the width of the PVC tape is to 1/2 of the original size.Step 10: After waterproof processing, use the outdoor bundling strap tobind the PVC tape tightly at the positions 1 cm away from the wrappingedges at both ends, to prevent aging and falling off of the PVC tape.Appearance of waterproofed outdoor connector

4.2 Installing the Grounding Clip
