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%)

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. 2nd to 3rd 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.

Sample Information with Comments3M < Scotch > 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.
