Usually better to connect to the house electrical system ground. For a temporary test I use a wire connected to the grounding pin of 3-wire plug inserted in a properly wired 3-wire receptacle or a cold water pipe with no plastic sections in it.

You might have to move your antenna if it is close to the noise source.
