WIDE-BAND UNTUNED AERIAL ( VERSIONS )

摘要

FIELD: antenna equipment. SUBSTANCE: propose wide-band untuned aerial may be used as TV receiving antenna to receive signal in metric and decimetric wave ranges. Aerial incorporates frame 1 to which medium point conductor 2 is connected and decoupling unit 3 that generally includes commutator and balancing device. Description provides for two versions of aerial with one feeder common for two ranges and with two feeders. One of them - 4 is meant for low-frequency range and other - for high-frequency range. This aerial may be used as room or built-in antenna for portable TV set. Description gives some experimental results. EFFECT: design of compact aerial providing for reception of signals in two considerably spaced apart frequency ranges. 11 cl, 6 dwgg
