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 universal kit is suitable for all coaxial cables (rigid, semi-rigid or flexible) of a maximum diameter of 11 mm. The conductive strip is rolled around the plaiting after having removed a length of 63 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. Mounting instructions (in pictures) are supplied with the kit.

Quick and easy assembly

The outer sheath of the cable must be removed by approximately 2 cm to expose the shielding. The supplied piece of braid and the cable tie are then placed over this exposed section, and when the screws are tightened, the insulating sealant is compressed to ensure a watertight seal. The cable tie is then connected to one end of the 16 mm² cable, the other end of which is connected to earth (M8x25 screw supplied).

Composition of the kit

• Cable tie whose inner face consists of a flexible metal plate and a ground braid to ensure electrical contact with the coaxial cable shield

• Collar clamping hardware consists of two M6x25 stainless steel screws

• 16mm² connecting cable, 1m long, equipped with lugs at each end

• M8x25 stainless steel screw for earthing connection.
