Horizontal long wire MW aerial.

[Crackle]

I see what you mean, in that circumstance yes I would.  
So what you are saying is, I am obliged to connect my nice new clean earth back to the mains earth.
So will fitting this earth make any difference at all to the RF signal from the new aerial, and will it help give a cleaner less interference signal?

The reason I thought I would fit a new earth was because I have noticed that interference is reduced a little if I disconnect the mains earth from the radio.


Thanks
Mike
