Earthing Radios and atu's


Hi All

Just a quick [sign in to see URL] it ok to earth my atu and my radio to the same earth wire?

can I have a wire coming from my radio to my atu then to my earth?
I was told to have to separate earth wires but the guy who told me isn't so knowledgeable when it comes to stuff like this so I thought id make sure.

Dont loop earths, Not sure why, but have one earth, and take a feed off the earth point to each bit of kit. maybe something to do with noise.

Re: Earthing Radios and atu's


Is it a mains operated radio, and do you have a PME electrical installation?

Decent answers depend a lot on answers to these questions, and the type of antenna used may also make a difference.

I've found no improvement in earthing any of my gear to a dedicated earth point, but I do use a vertical antenna with a fair few buried radials - this serves as a decent earth for the radio in my case.

12 volt PSUs can simply be earthed via the mains.

Here's a generic answer:
An ATU will share the same earth as the radio as the coax braid is the connection between them - don't add another earth as there is no point. Simply earth the ATU to your earth rod and the rest will follow electrically. If you are using a DC ground antenna like a GP27 half-wave, earthing the support mast will also do the job.

Beware of PME issues if you have a PME installation. It should be prominently marked at the meter/fuse box. If you have a PME installation, our advice will be different for safety reasons so let us know.
