Lightning conductor for ametuer radio antenna mast - electrician says regular PVC sheated yellow green wire is ok from mast to earth rod

Former Community Member

As per title I am getting a corner of my house setup as a radio shack and wanted to protect it appropriately.

The antenna is made of fibre glass but sits on an aluminium pole that brings the total height to 10m tall (only house in the area).


We have agreed to setup an earth rod below the antenna mast and earth it but the question is - will regular 35mm green/yellow sheated earth be good enough to provide earthing for antenna mast while being exposed to the elements? How long will it last?


Any thoughts on the electrical setup for the radio? We are planning to use the same earth rod and make a TT island for the power socket that feeds the radio unit (as main electrics is PME). The radio will be fed electric connection through an MCB by taking power from the main distribution box protected by a Type 1/2/3 SPD (I have 3 phase 100A supply from DNO) and we will use the earth rod for earth supply.


The radio unit will be powered by a seperate consumer unit which gets it's earth supply from the rod (I might also get a Type 1 SPD in the TT island consumer box).


The antenna and the TT island powering the radio will be linked by a 700A rated earth bar enclosed outside the property in an IP65 enclosure.


Appreciate any thoughts on my setup.
Am I being overkill and do not need a TT island for my radio setup? Will earthing the antenna be sufficient?

    . . . Everything is underground (I believe it is 33kv because on the map it says HV and the last time the DNO was doing some work I looked at what they were digging up and there were almost 15 cables coming out and atleast 1 or 2 of them was as wide as my wrist. . . 


    The size of the cable indicates it’s current carrying ability, not its voltage. The voltage should be written on the substation door / gate along with its name. I very much doubt it 33kV. It is likely to be 11kV, but depending on where you live could be 22kV.
