Microwave antenna of Contents Microwave antenna Transmitting or receiving antennas working in meter wave, centimeter wave, millimeter wave and other bands are collectively referred to as microwave antennas. Microwaves are mainly propagated by space waves. In order to increase the communication distance, the antenna is erected higher. Among microwave antennas, parabolic antennas, horn parabolic antennas, …
What’s the antenna of Contents what is the antenna An antenna is a device that can effectively radiate electromagnetic waves to a specific direction in space or can effectively receive electromagnetic waves from a specific direction in space. We use the analogy of communication between people. The antenna is our ears and mouth. We convert …

Signals emitted by satellite transponders Satellite transponders transmit signals either in C-band or KU-band, and these signals pass through space into terrestrial satellite TV reception systems. The role of satellite ground receiving antenna The role of the satellite ground receiving antenna is to receive the weak satellite signal propagated from space to the ground, and …
After you find that you can’t receive the program, don’t worry about it. The exclusion method should be used to gradually eliminate all possible causes and identify the problem site. 1. First check whether the connection between the receiver and the TV is correct. 2. Then check whether the parameter settings of the receiver are …
What is the founction od satellite finder of Contents What is a starfinder The star finder, also known as the star finder, is a simple instrument used for the installation and adjustment of the satellite receiving antenna. It can be used as an indicator to adjust the antenna direction, feed position and polarization angle, etc. …

When installing the parabolic antenna, it is generally installed according to the structure diagram provided by the manufacturer. The antenna structures of various manufacturers are basically the same. The structure of the antenna reflector has two types: integral forming and splitting (the reflector above 2M is basically splitting). The tripod mainly includes pole mount tripod …
Feeder for satellite TV receiving antenna The role of the feeder Speaking of satellite antenna, we have to mention the satellite feeder (satellite collector), in the satellite TV receiving antenna, the satellite feeder as the primary radiator of the antenna, is the heart of the antenna. Its role is to organize the electromagnetic wave reflected …
A large number of wireless devices need to be deployed during the construction of 5G network base stations. The number of these wireless devices is very large, and the installation and deployment sites are also very complicated. There will be mutual interference problems between them. During operation, the channel often transmits wrong signals, which affects …
reasons for the low quality of satellite TV signals The deterioration of satellite TV signal quality is manifested in the increase of mosaics, pauses, loss of receiver locks, and even crashes,the first feeling that give people is to suspect that there is a problem with the TV station or satellite – reason is that the …
