Grounding Wire to copper pipe for cable
One option would be to see if you could move that connection to a location where you have grounding available easily. That is just a COAX cable, for TV service or internet, via satellite or cable. It can be mounted anywhere along the line run, but preferably as close to the beginning of the run, or at least prior to any device connections. The installer found a copper pipe and just grounded there. As for the comment of leave this as is, if you disconnect the pipes before and after, then it is no longer a ground connection.
