摘要
A double frame antenna for television receivers, broadcast receiver reception of VHF to UHF, VHF radio systems, etc. (Fig. 1). Previously known embodiments had the disadvantage that vertically polarised transmitters in VHF Band III could be received with only impaired video quality. As a result of the arrangement in the case of the present invention: antenna-circular form for the magnetic field in conjunction with the telescopic rod, leading out of the circular form, for the electrical field, the antenna can be tuned to any channel by varying the length of the telescopic rod to the reception frequency. The present antenna invention is suitable and can be used as an indoor antenna for television and radio, as a car radio, car telephone or ship antenna, and for amateur radio. IMAGE
