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. Location. A star finder is essentially a microwave signal level display amplifier.
Star finder function
The function of the star finder is to adjust the satellite antenna to the best receiving position, so that the satellite signal can be received clearly and stably. Nowadays, the development of satellite TV receivers is very rapid. The technology of receiving satellite TV signals has become more and more abundant under the research of many satellite TV enthusiasts. Under their extensive publicity, the application of this technology has become more and more popular. Some wonderful satellite TV programs can also be received in some remote mountainous areas.
The principle of the star finder
The principle of the star finder is very simple, that is to integrate the set-top box and the screen remote control, directly connect it to the high-frequency head (noise-reducer) through the feeder, and locate by moving the antenna (pot). This is a handheld star finder. The principle of star finding. There is also an old-fashioned method of determining the satellite position through readings. The direction with the largest reading is the satellite direction. The principle should be to amplify the field strength signal.
How to use the star finder
1. Connect one side of the finder marked with “TO LNB” to the antenna tuner, and the other side marked with “TO REC” to the receiver, and turn on the receiver and TV.
2. After the receiver is turned on, the voltage supplied by the receiver is 13-18V. Check whether the light of the star finder is on. If the light is on, it means that the star finder is working normally.
3. Set the data of the satellite to be received in the receiver. (including local oscillator frequency, downlink frequency, symbol rate, polarization, etc.) and open to signal strength, signal quality cursor status.
