Appendix C: Grounding and RF protection122 Alternative grounding for timber hullsC.8 Alternative grounding for timber hullsC.8.1 Grounding the terminalThe terminal must be grounded with the short antenna cable and theGrounding kit (accessories). Further, the terminal must be grounded at itsgrounding stud in order to ensure a proper grounding if the short antennacable is disconnected.The ground connection must be established at a dedicated RF ground (eithercapacitive or electrical coupled). Bear in mind that the antenna groundconnection is to be made at the same electrical ground potential as theterminal (see Grounding the antenna).C.8.2 Grounding the antennaIf the mounting base of the antenna is electrically connected to any otherground potential than the terminal (e.g. Lightning Ground), the antenna mustbe isolated at its mounting bolts by means of shoulder bushes and washers -see page 126.However, a ground connection must be established via one of the mountingbolts using a separate ground cable. The ground cable must be routed paralleland in close proximity to the shielded coax cable hence connecting theantenna to the terminal Grounding kit. A tinned heavy gauge wire (min. 6mm2 ) can be used for this purpose - see page 123.
