An apparatus for testing mobile phones of the type having a protruding antenna includes an air chamber which provides radio frequency shielding and which surrounds the mobile phone under test, a radio equipment automated testing circuit, an antenna mounted within the air chamber which includes a hollow cylinder of electrically insulating material for surrounding a portion of the protruding antenna during testing, a thin, electrically conductive film mounted on a surface of the hollow cylinder, the film including a first band portion extending in a circumferential direction entirely around a peripheral surface of the hollow cylinder, a finger portion extending from the first band portion in a direction parallel to an axis of rotation of the hollow cylinder, the finger portion tapering to a point at a location furtherest from the band portion, and a second band portion having a width that is smaller than the width of the first band portion, and extending from the point of the finger portion in a circumferential direction only partially around the peripheral surface of the hollow cylinder, and an electrical connection to the point of the finger portion for connecting the antenna to the radio equipment automated testing circuit.
