Problems solved by technology
[0004] Under the conditions of satisfying the electrical and mechanical properties, the traditional antenna usually has a large structural size and heavy weight. At the same time, as the height of the antenna increases, its structural size and weight increase sharply, resulting in complicated erection and disassembly, let alone satisfying portable requirements

Description
technical field [0001] The invention relates to an antenna device, in particular to a digital TV signal receiving device. Background technique [0002] All devices that use electromagnetic waves to transmit information require antennas. Therefore, in the fields of broadcasting, communications, meteorology, aerospace, and electronic countermeasures, antennas become a key component of the system. [0003] At present, there are many forms and types of digital antennas, among which pot-type antennas and telescopic rod-type antennas are the most widely used. With the increasing number of portable equipment, people's requirements for antennas are getting higher and higher. Antennas must not only have excellent electrical signal receiving functions, but also be easy to erect, disassemble and decorate. Small, easy to erect and collect, but also has good decorative performance. [0004] Traditional antennas, under the conditions of satisfying electrical and mechanical properties, u...
