Essentially, suppression is attained by providing a low resistance path to ground for stray currents. The methods used include shielding the ignition
and high frequency wires, grounding the vehicle with bonding straps, and using capacitors and resistors.
The primary components are:
Wire Shields. Some of the high voltage or frequency wires have the possibility of electrical leakage through the insulating cover. The "wire shield" is
a protective covering over the wire to aid in the reduction or elimination of such leakages. These leakages, if not restrained from the radio, would
cause undesirable interference.
Shield may be of many types of material rubber, steel, stainless steel, lead, plastic, etc.
