Product Description:

This special frequency S band LNB has low-noise and down-converter functions to amplify and down-convert the satellite signal transmitted by the feed. Besides, it helps to convert the band signal and transmit it to the coaxial cable. As a kind of low-frequency converter, it consists of a high performance mixer and oscillator. The low noise amplifier section of the LNB amplifies this weak signal while adding the minimum possible amount of noise to the signal. The satellite high-frequency signal is first amplified in order to convert the high-frequency signal. What' more, it amplifies again to facilitate the transmission of the coaxial cable and the operation of the satellite receiver.


Product Feature:

It picks up the signal directly from the two active probes, which helps to avoid the loss of the signal received by the servo motor system.

The image distortion caused by mechanical rotation of the probe is eliminated. 

The ultra-low coefficient noise temperature completely replaces the mechanical rotary probe structure using traditional electric feed.

The internal electronic switching circuit of this special frequency S band LNB selects the corresponding signal to ensure stability and reliability.
