Be sure to ground your car's biggest radiating antenna -- the exhaust
pipe. It runs from the engine block back about 20 feet, with insulated
standoffs to keep it ungrounded. Run a piece of flexible braid from the
frame to the rear end of the pipe. That reduced my noise by 80%. All of
the other grounding added perhaps 5-10% more.
