Earthing rod garden moving

[Jaqqqqqq]

Hello experts.
I have a black cable running from the loft , up the garden, under the garden.

Can I move the rod to a different part of the garden?

The plug attached works and would be helpful to use.

Any advice would be great thank you.

In order to move the electrode, you will need to prove the impedance of the electrode's new position. I take it is the earth for a shed protecting the SWArmour cable install. If you need to extend the existing earth then it is not a good idea joining it as the cable joint would probably end up buried. Best get an electrician to move it & test.
