Title:
【発明の名称】多帯域アンテナ
Document Type and Number:
Japanese Patent JP2567384
Kind Code:
B2
Abstract:
A plural band telescopic antenna, including a band for frequencies much higher than the frequencies of the AM/FM band, is realized by making one telescopic section into a dipole high frequency antenna with its coaxial cable feed line extending through the telescopic antenna to the feed point of the one section. A double-tuned dipole embodiment and different arrangements for coupling the feed line through a rotational drive force applying mechanism are shown. In one embodiment, the line feed is also used for coupling mechanical extension and retraction forces to the one section.
