Embodiment Construction

[0022] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0023] See attached Figure 1-3 , a combined CB antenna in the UHF frequency band, including a base 1, a short antenna 2 and a long antenna 3, the base 1 is connected to the short antenna 2, and the long antenna 3 is detachably connected to the short antenna 2 , the short antenna 2 and the long antenna 3 include antenna housings 20 and 30, the antenna housings 20 and 30 are made of tapered glass fiber material, which can reduce wind resistance, reduce the weight of the antenna, ensure the strength of the antenna and make it more beautiful. The antenna shells 20 and 30 are integrally formed by injection molding, and the structure is firm, ensuring the reliability of the connection.

[0024] Further, the short antenna 2 is connected to the long antenna 3 through a connecting piece 4 . Specifically, the upper and lower parts of the connector 4 are provided with...

Abstract

The invention provides a combined type UHF frequency range CB antenna comprising a pedestal, a short antenna, and a long antenna; the pedestal is connected with the short antenna; the long antenna is detachably connected with the short antenna; the short antenna and the long antenna respectively comprise an antenna housing made of taper glass fibers; the antenna housing uses the taper glass fiber to reduce the wind resistance and antenna weight, thus ensuring the antenna usage intensity, and providing more beautiful appearance; the short antenna and the long antenna are threaded by a connector, and different connectors can be replaced so as to match with long antennas of different calibers; in addition, a screw is added for fixation enhancement, thus ensuring the long antenna not to loosen in vehicle-mounted usage; the short antenna and long antenna are installed in a separated mode; the antenna only needs to be mounted once, and can be freely switched to high or low gain antennas, thus complying with different usage conditions, and saving cost.

Description

technical field [0001] The invention relates to a combined CB antenna of UHF frequency band. Background technique [0002] CB (personal communication in citizen band) antennas are mostly used for vehicle communication, which can provide road conditions and driving guides, so as to strengthen the connection between vehicles when driving and increase driving safety. The structure of the existing CB antenna is mostly a telescopic antenna body, which can be adjusted in length according to the needs in different environments. This type of antenna is easily broken and the signal is unstable when it is applied to automobile communication. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a combined UHF frequency band CB antenna, which has a stable structure and wide applicability. [0004] Technical scheme of the present invention is: [0005] A combined CB antenna in the UHF frequency band, comprising a base, a short antenn...
