1/2" coax grounding kit

This method of earthing the plaiting of coaxial cables is systematically used on professional radioelectrical installations. As a general rule, it is placed next to the antenna, at the base of the mast and before the cable enters the equipment room. It contributes to the discharge of static charges and protects the installation against lightning strikes.

Radio amateur stations are equally concerned because their masts and antennas are also exposed to thunderstorms. The minimum precaution consists in putting the earthing kit on the outside of the building, in the area of the cables entering the equipment room.  If the kit is placed there, protection can be reinforced by placing a second kit at the base of the mast to earth it itself.

Lightning doesn't know the difference between a "radio earth" and a "domestic earth" ; it takes the shortest route and not necessarily the expected route. Equipotential bonding is therefore essential for common earths.

This kit is suitable for all coaxial cables (rigid, semi-rigid or flexible) of a diameter of 1/2 inch. The conductive clip is rolled around the plaiting after having removed a length of 40 mm of the outer insulation. Waterproofing is perfectly assured by insulating mastic and flexible adhesive tape. Electrical contact is reinforced by the use of appropriate grease.

Composition of the kit

• Clip equipped and copper terminal

• Bolts, nuts and lock washers in A4 stainless steel

• Waterproofing mastic

• Flexible adhesive tape

• Conductive grease for nuts and bolts
