Cable Routing

52

Cable Routing Guidelines  Cable Routing Guidelines  Weather Seal Application  C Bend near LNBF  Service Loop near Mast

 Application of Cable Tie  S Bend Application  C Bend on edge of the wall  C Bend while laying cable at 900  U Loop & Sealant Application  Through Hole for Cable Laying  P Clip Application

 Cable Routing Precautions ( Do’s & Don’t ) 53

Cable Routing Guidelines Weather Seal Application  Ensure / Check for Weather Seal, It should be fixed at LNBF port before connecting the connector to LNBF

 Connect the Cable to LNBF  Tighten Connector by Hand

 Finally Tighten the connector with open ended spanner

Benefits :  Weather Seal prevents Water Ingress / Seepage inside the cable  Weather Seal prevents Cable Damage, Satellite Box Failure & Connector Corrosion due to Water Ingress/ Seepage

54

Cable Routing Guidelines C Bend near LNBF  C Bend should be always made near LNBF

C Bend Tie Wrap

Benefits : By Application of C Bend the “Bend Radius” is maintained, thereby :  Prevents Cable Damage near Connector at LNBF end  Less Signal Losses ( as the Sharp Bend is avoided )

55

Cable Routing Guidelines Service Loop near Mast  Service loop ( Only One Round ) should be tied with Mast

Service Loop

( 8~ 9 inch Diameter )

Benefits : -

( 0.20 ~ 0.22 Meter Diameter )

 Service Loop can be used for future service Applications like Re - Connectorisation etc.

56

Cable Routing Guidelines Application of Cable Tie  Loose / Hanging Cable should be properly tied with Cable Tie / P Clip

Tail of the Cable Tie should be trimmed properly with maximum tail length of 5mm (after cutting)  Always use Company Approved Cable Tie

Benefits :  Prevents Cable damage due to rubbing with wall edges / metallic parts  Improves Aesthetic Look of the Installation

Precautions :  Avoid over tightening of Tie warp as it may damage Cable Jacket which may results in Water Ingress / Seepage  Width of Cable Tie should be more than 5mm

57

Cable Routing Guidelines S Bend on edge of the wall  S - Bend should be always made, while routing the Cable vertically from one side of wall to other side of the wall

S Bend ( Outer Edge of Wall )

Always use Two P Clips ( Opposite Direction ) while putting any bend / Loop

Benefits : By Application of S - Bend the “Bend Radius” is maintained, thereby :  Less Signal Losses ( as the Sharp Bend is avoided )  Prevents Cable Damage due to friction with Wall (Outer Edge Case )

58

Cable Routing Guidelines C Bend on edge of the wall ( Inner & Outer )  C-Bend should be always made while routing the Cable at Inner & Outer Edge of the Wall  Cable should be laid through PVC Conduit or use Double sided Tape in case of Outer Edge

C Bend ( Inner Edge of Wall )

C Bend ( Outer Edge of Wall )

PVC Bend ( Outer Edge of Wall )

Benefits : By Application of C Bend / PVC Bend the “Bend Radius” is maintained, thereby : -

 Less Signal Losses ( as the Sharp Bend is avoided )  Prevents Cable Damage due to friction with Wall (Outer Edge Case )

59

Cable Routing Guidelines C Bend while laying the cable  C - Bend should be always made while routing the Cable on the wall from vertical to horizontal or vice versa

More than 90o C Bend

Benefits : By Application of C - Bend the “Bend Radius” is maintained, thereby :  Less Signal Losses ( as the Sharp Bend is avoided )

60

Cable Routing Guidelines U Loop ( Drip Loop ) before cable entry in house Sealant Application  U – Loop should be always made before cable entry in the house  Sealant should be applied from both sides of the hole with no air Gap  Use appropriate bit for Wooden or steel Frame Sealant Application Without any air gap C Bend ( more than 90 degree ) Height Minimum 20cm

U Loop

Benefits : -

Diameter Minimum 12cm

By Application of U – Loop & Sealant the below mentioned can be prevented  Water Ingress / Seepage inside the house  Satellite Box Failure due to water Ingress / Seepage

61

Cable Routing Guidelines Through Hole for Cable laying  It is recommended to drill through hole for Cable entry from Inside to Outside

30 o Angle

Outside

Inside House Wall

 Through Hole for Cable entry should have a slope towards outside the House

 While drilling through Hole drill machine should not be in hammer Mode  There should not be any damage on the inside / outside surface of the wall

62

Cable Routing Guidelines P Clip Application  Always use company approved/recommended proper Diameter P-Clips

 Nail of the P Clip should be downwards, in case of Horizontal laying of Cable Nail should be downwards

 Cabling should be Straight  P-Clip should not be equi – distance

Precautions :  Cable should not deform / damage while P-clipping with hammer  P Clip should neither be loose nor over tightened

63

Cable Routing Precautions ( Do’s & Don’t ) Topic  Kinking / Bending of the Cable

Do’s  Take care while pulling cable to prevent cable from Kink / cut.

Don’t  Never use Kinked / Bend Cable.

Benefit :-

Disadvantage :-
