Problems solved by technology

After repeated tests and comparisons, it was found that the main reason for Ku signal attenuation is that rainwater accumulates on the antenna’s reflective surface and feed port, especially after condensing into water droplets, which strongly scatter and attenuate Ku signal, making the reception The effect becomes worse

Embodiment Construction

[0025] In order to better illustrate and describe the content of the present invention, the following description will be carried out in conjunction with the accompanying drawings and implementation examples:

[0026] Have Figure 1-Figure 3 As shown, the present invention discloses a method for improving the signal receiving efficiency of a satellite TV signal receiver, and the specific steps are as follows:

[0027] (1), for the metal paraboloid 7 of the satellite television signal receiver, the metal paraboloid 7 that cannot move up and down originally is transformed into the movable metal paraboloid 7, namely carries out the structural transformation to the metal paraboloid 7;

[0028] (2), the metal paraboloid 7 that is originally a whole is turned into a metal paraboloid 7 formed by splicing many triangular blocks 4, and the connections between the triangular blocks 4 are all active connections, that is, each triangular block 4 is connected to the entire metal paraboloid...

Abstract

The invention discloses a method for improving the signal receiving efficiency of a satellite television signal receiver, which comprises the following steps of: aiming at a metal paraboloid of the satellite television signal receiver, converting the original metal paraboloid which cannot move up and down into a movable metal paraboloid, namely structurally transforming the metal paraboloid; the original integral metal paraboloid is changed into the metal paraboloid formed by splicing a plurality of triangular blocks, and the triangular blocks are movably connected, namely, each triangular block is movable; the signal searching speed of the satellite television signal receiver can be improved by changing the elongation of the actuator and establishing a net-shaped support frame.

Description

technical field [0001] The invention relates to the related field of satellite signal equipment development, in particular to a method for improving the signal receiving efficiency of a satellite television signal receiver. Background technique [0002] Digital satellite television has developed rapidly in recent years. It uses geostationary satellites to transmit digitally encoded and compressed television signals to the user's end. A form of broadcast television. The digital TV signal is sent to the front end of the cable TV, and then converted into an analog TV by the cable TV station and sent to the user's home. This form has been popularized and applied in many countries around the world for many years. [0003] When watching satellite TV programs, the signal is unstable, the picture has "mosaic", the sound is intermittent and other poor quality phenomena. The common reason is that the signal strength is in a critical receiving state. You can re-adjust the antenna orien...
