A good quality fully automatic car aerial that is designed to fit negative earth cars & is electrically operated & powered by the car battery. The aerial will only extend when the radiocassette is switched on & is retracted when the radiocassette is off so greatly reducing the risk of the aerial being damaged by vandals. Power & control connections to the aerial are made by three wires green & red which have bullet type connectors & 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 onoff switch of the radio-cassette. Black is connected to the car chassis or negative battery terminal.

The assembly is 335mm in length with the aerial completely retracted & 22mm in diameter. A good quality fully
