hi
my new antenna mount is a through-body type, ie you drill a 10mm hole in the bodywork to fit it, it came with 2 plastic moulded washers that look like they sandwich the body in between, I assume the are weatherproofing/cosmetic, I am mounting mine on the wing so don't need them to be waterproof, my wing top is too thick to use them so
can I just fit it through the wing and have it in electrical contact with body or does it need insulating from the body?
Ta
Mike
