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

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?

    For some reason the Earth Mat is under my property ! I have no idea how they managed to do that or if it is even accurate.

    If it is on your land, you might be due some payments from the DNO. My Dad used to have a couple of HV poles and a transformer in his garden and got a few quid a year on account that it served next door as well as him. He missed out on the payments for several years when he first moved in as apparently they payments don't transfer automatically when the land changes hands, so each new owner has to make a specific claim. I'm sure the money wouldn't be significant to you, but the process of making a claim might be an easy way of getting the DNO to establish exactly what's on your land and what isn't. I know from experience that such services maps are not always accurate - I know of a house whose sale was delayed because the water authorities map showed a main sewer crossing the front garden - in reality their database was missing one inspection chamber on the bend of the road outside and the computer had just joined the dots and so shown the sewer as a straight line between two distant man holes, cutting the corner of the road.

    But then they will want to add leeway rights on the title deed and any further development on that plot of land will need their approval.

    If I left it in-situ in the future if I wanted to rebuild over it I could just serve them notice and proceed to dig out whatever is there (will allow a 60 day time or whatever for rectification).


    Apparently the DNO offered the land to the previous owners for sale but they did not take it up, would love to buy it off them just do not know whom to contact :)
