    Maybe this will help .A good quality fully
    automatic car aerial that is designed to fit negative earth cars and is electrically operated and powered by the car battery. The aerial will only extend when the radio/cassette is switched on and is retracted when the radio/cassette is off, so greatly reducing the risk of the aerial being damaged by vandals. Power and control connections to the aerial are made by three wires: green and red, which have bullet type connectors, and a black wire which has an eyelet connector. The red must be connected to the positive battery supply via a suitable fuse rated at 5A. Green must be connected to the power antenna lead output of the radio-cassette, or directly to the on/off switch of the radio-cassette. Black is connected to the car chassis or negative battery terminal. The antenna when fully extended is 0.81m in length, and is supplied with 1.3m of screened cable which is terminated in a standard car aerial plug. The assembly is 335mm in length with the aerial completely retracted and 22mm in diameter.
