I need to re ground an antenna. Firstly, can someone explain to me how this is done and secondly.... what are my chances of getting electrocuted while I do this?

You have two choices. You can do a "group loop" Which is easier and a bit safer but you might get unwanted static and noise. Or you can run one heavy gage wire from the ground on the battery back to the distribution block and ground everything from there.

I would go with the second option. If you do make sure the wire you use to ground to the battery is a very heavy duty grounding wire. Do not use any old wire for that.
