An articulating elongated inspection neck effective to shield radio frequency interference. The inspection neck includes a series of individual electrically conducting parts each having a passageway there through. The parts are pivotally joined together with the passageways aligned along the length of the neck. A self-adjusting electrically conducting member connects immediately adjacent individual parts in electrical communication. The self-adjusting members maintain electrical communication between the parts throughout movement of the parts during flexure of the neck. Consequently, these members maintain electrical continuity along the length of the neck. The spacing between the parts is sized to be barrier to predetermined radio frequencies. |
