Abstract
An active aerial for use in car radios and aerial 'arrays' comprising an aerial element and an aerial connected thereto. In order to obtain a low distortion and a good signal-to-noise ratio in spite of the presence of protection diodes to prevent overloading of the amplifier by atmospherics and in spite of contamination of the aerial etc, the input of the active portion of the amplifier is virtually grounded. To this end, the amplifier is preferably an operational amplifier having a high gain factor, the signal input of which is connected to ground, both the signal coming from the aerial element and a signal fed back from an output of the amplifier being applied to the inverting signal input.
