Lighting protection via 10mm bonding cable

I'm pretty sure its a requirement to earth TV aerials and sat dishes. Maybe that's what it was for? 3m pole tho does sound like it could have been a radio mast?
I'm sure if it was lightning protection the installation requires surge protection but I'm no expert on lightning protection

You had better tell SKY then

Also some good info to download here

In the past I've had some good information and help from the technical support people over the phone from both Wallis and Furse so may be worth a call. Had a chat with a guy at Furse once after I had faxed some info to him phoned him to discuss the project and his response was it would be more dangerous to install lightning protection than not installing it so lightning protection ain't the be all and end all solution on some sites

With regard to the OP it sounds like this has possibly been some sort of comms installation at some time, it is not clear in the post if there is actually a lightning protection system installed and this is just a bond to the MET or if this conductor is the sole earthing point if it is the latter it would be better disconnected.

I've seen quite a few iffy installations on sites when I was installing a lot of comms kit a number of years ago including a failed ground termination on a lightning protection system on one site and the whole of the roof system was earthed on two coax shields from a couple of other radios on the roof, only became apparent because the kit we were installing suffered some interesting interference problems
