Digital television communication antenna with function of signal search through precision lifting

Abstract

The invention relates to a digital TV communication antenna capable of accurately lifting and searching signals, comprising a base plate, the lower end of which is installed on a precision lifting device, four pillars are arranged symmetrically on the outside of the upper surface of the base plate, and the upper ends of the four pillars are installed with Ring slide rail, the four pillars play the role of evenly supporting the ring slide rail, a rotating steel ring is installed on the ring slide rail through sliding fit, and an inner gear ring is arranged on the inner wall of the rotating steel ring, and the inner gear ring is respectively connected with four The transmission mechanisms are connected, and the four transmission mechanisms are symmetrically installed on the upper end surface of the base plate. The present invention can realize the function of digital motor antenna to precisely lift and adjust the search signal and automatically adjust the signal receiving inclination without manual operation, and has the functions of automatically adjusting the search height of the signal, high precision of lifting adjustment, automatic adjustment of the signal receiving inclination, high precision of the receiving inclination, and signal search It has the advantages of good effect, simple operation and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a digital TV communication antenna capable of accurately raising and lowering search signals. Background technique [0002] The antenna is a converter whose main function is to transform the guided wave propagating on the transmission line into electromagnetic waves propagating in the unbounded medium. Antennas are used in radio equipment as components for transmitting or receiving electromagnetic waves, and are widely used in radio communications, broadcasting, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems. Antennas can be divided into communication antennas, broadcast antennas, TV antennas, and radar antennas according to their uses, among which TV antennas are the most widely used. [0003] TV antennas can be seen everywhere in our lives. Since signal transmission towers are widely distributed in cities, th...
