Default Earthling DSTV dish.

Hi,

What’s the best way to earth a dish?

And how do I know if my dish is currently earthed or not without climbing into the roof?

I can see nothing from the outside. Only a LNB with the single wire going into the building.

People have recommended a surge arrestor as well as an earth spike (although I’d prefer it to be earthed directed to the earth leakage, which afaik is a legal requirement anyway).

Is it an requirement for a electrician to do it? Or does the responsibility lie with the installer?

Reason I ask, in as much as 1 year, I’ve have 3 lighting strikes to the dish taking out my AV equipment one after the other…

The legal requirement is that any antenna placed at the highest point on a building MUST be earthed. If the antenna is NOT the highest point on a building, it does not have to be earthed.

Earthing must be done by an electrician or an earthing specialist. Installers are very rarely electricians or earthing specialists and are therefore not responsible for doing the earthing, that is up to you to arrange.

NO you DO NOT want to tie this to the earth in your DB board.

A good "earth" would tie the antenna earth to the earth provided for your installation on the outside of the building which should be tied to the earth provided in the DB board.

A separate earth peg etc is acceptable, but in my opinion is not as good as a tie to the property earth.

Seriously re consider the location of the antenna and move it away from being the highest point on the building as a start and then get it earthed.

Thanks for the info.

Well technically it's not the highest point of the house but it comes pretty damn close.

It's a bit of a tilted two storey "sink plaat" roof. And the dish is way up there almost level with the roof.
