1. Water Proof for Coaxial Cable Termination 1/2 Shield packing for cable fixing ( effectively depend with cable size ) Shield packing for cable fixing. The vibration of the cable always breaks this packing and shield wires of coaxial cable. Water infiltration No water proofing points (moving parts) SURGE ARRESTOR COAXIAL TERMINATION 2nd Step Shield with self bonding tape (>2mm thickness). Shielding of cable connection point: Connect grounding cable to arrestor body. 1st Step Point shielding and leveling: Use Self Bonding (autohesion) rubber tape, it pulls (stretch) until becomes thin and then wrapping. (Self bonding tape is possible stretch 1,000%)

2. 2/2 Use a PVC protection tape, It pulls at 1st laying for fastens up the self bonding (autohesion) layer. Overlap the PVC tape to half width. 2 nd to 3 rd laying, it does usual wrapping method. The direction of the winding always ends on the side of ODU/ANT to prevent the infiltration of water. Never use an Vinyl insulating tape !!. The tape which has a elasticity (soft) can not use. The PVC protection tape has only a few stretch margin and it has high resistance for outdoor use (compared with the usual vinyl insulation tape). 3rd Step Total Shielding: Use Self Bonding Tape, It pulls (stretch 100%) tape to ensure effective bonding (fusion, autohesion) and then wrap until sufficient thickness. When there is a crack, use a few silicon shield for grounding cable. Shield with self bonding tape (3mm thickness aprox.) ODU/ANT side 4th Step Protective Taping (3 layer) Cable tie ODU/ANT side The rubber fusion layer

3. Sample Information with Comments 3M 130C Self Bonding ( Autohesion ) Tape Water proof and Insulation Note: It does an autohesion (fusion) when the tape is stretching (pulled). Generally, it winds in the 100 % pulled condition. It adjusts Stretch from 100 % to 1000 %, depending by the condition or status to use. Caution: Vinyl or PVC tape doesn't have any water proof feature, only it has insulation and protection.
