Abstract
Abstract A dipole antenna connected across the input of a transistorized push-pull amplifier. The output of the amplifier is applied to a conventional small RF receiver. A first embodiment includes a filter network connected to the antenna for supplying bias voltage to the amplifier. A second embodiment includes a DC battery for supplying the bias.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
117 words
An antenna assembly comprising driven elements having respective feed points, a push-pull solid-state amplifier having input terminals connected to the feed points through an electrically direct path, and tap-off terminals connected to the amplifier output for making available amplified electromagnetic signals for utilization by a receiver front end section, reflector elements positioned in spaced relation to the driven elements, the antenna assembly further including means for converting alternating current to direct current, means connected between the reflector elements and the input of the converter means for supplying received radiation power to the converter means, and means for connecting the output of the converter means to the power input terminals of the amplifier for delivering biasing power thereto.
