Which earth wire? Mains or External RF earth?

If the L or N to chassis leakage is OK, then you can wire the mains earth wire direct to chassis, using only a 3 core flex. If the Leakage is NOT OK, then you have a problem anyway as the RCD may trip and there must be a fault.

Only an RF earth should optionally use a 1000nF 1kV capacitor to stop Mains Earth wirring hum loop to your RF outdoor Earth spike(s).
