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?

    Ok thanks for the steer, the idea of TT was not to cut out noise but to put everything in the radio system on a common earth potential (which it seems like might not be required).


    I have one of the devices like the one below (not the exact same one) but looks like it needs an earth connection as well, so I might just put it in an IP65 enclosure outdoors and earth to a rod and bring the coax inside.

    What do you think about this? Do I really need to earth the coax surge protection device (that is what the small screw is for).

    What is my risk profile if i just say sod this all, bring the coax in and run off the mains PME earth but just be careful anytime the weather is off?
