Abstract

The invention discloses an antenna tuner which structurally comprises an antenna device, a wiring terminal, a fixed sheet, a protective shell, a signal adjusting terminal and a circuit groove box. When a device is used, a frequency raiser mechanism is arranged. In the working process of the antenna tuner, for a surrounding-variable environment, when the frequency of a transmitter is changed, the impedance between the transmitter and the antenna is not matched, the radiation power is reduced, the operation is troublesome, fine adjustment is difficult to perform, the frequent mismatch of the antenna is caused, and the structure of the antenna cannot be frequently changed, the above problems are solved by the invention, the equipment is matched with a bearing frame through a linkage swing rod; the limitation of a traditional antenna fixing mode is broken through, meanwhile, an auxiliary supporting scheme is provided for signals of an antenna mast, the coverage points of the frequency raiser can be flexibly increased through signal strips, the impedance between the transmitter and the antenna is effectively adjusted, and the signal feedback is efficiently matched and more convenient.

Description

technical field [0001] The invention is an antenna tuner and belongs to the field of tuner equipment. Background technique [0002] The antenna tuner is an impedance matching network connecting the transmitter and the antenna. It can match the impedance between the transmitter and the antenna, so that the antenna has the maximum radiated power at any frequency. It is widely used in ground, vehicle, ship Carried and aeronautical shortwave radio. [0003] The prior art has the following deficiencies: during the working process of the antenna tuner, because it is sometimes installed in a relatively high altitude environment, facing the changing environment around, when the frequency of the transmitter changes, the distance between the transmitter and the antenna If the impedance does not match between them, the radiation power will be reduced. It is very troublesome to operate, and it is difficult to make fine adjustments, resulting in frequent mismatching of the antenna and t...
