I have a skyview digital satellite PCI card. I installed the card in PC. I can tune channels using KU band universal LNBs. But to program channels from C abnd LNB i need to Input LNB High Frequency, LNB Low Frequency, and LO switch Frequecncy. I have only information that my LNB frequecncy is 5700MHz. Please help me to find out what are the other parameters to input

Universal Ku band LNBs have internal capability to switch polarisations and to switch local oscillator frequencies. For example Vertical or Horizontal polarisation by altering the DC supply volts 13 volts or 19 volts and to switch the LO frequency from 9.75 to 10.6 GHz using a 22kHz tone OFF/ON.

C band LNBs are normally single polarisation, with the direction defined by the half dipole pin inside the rectangular waveguide and with single local oscillator frequency.  

If your C band LNB is simple like this, then put the same LNB LO frequency into both LO frequencies on the screen and turn the 22kHz tone off.  It then does not matter what voltage you select, 13v or 19v.

Check the 5700 MHz figure on the label.  It is more likely one of these: 5150, 5750 or 5950MHz.  The 5150 is used worldwide, the higher ones for some Indian satellites, I think.

If you have some unusual complex C band LNB with options, you need to read the LNB data sheet.  What are the manufacturer and model number and what exactly does it say on the label.

Best regards, Eric.

A satellite TV PCI card for a PC is an alternative to having a satellite TV set top box.

Read here about various cards:

Use the Google search box on page https://www.satsig.net/satsig-search.htm to invstigate further alternatives and find more details of specific models.  If you want to watch paid for satellite TV you will need a card with provision for the insertion of your bought viewing card.  I am not sure this will work and would suggest a normal satellite TV set top box in such cases.

www.lyngsat.com will give you some ideas about possible satelite beams contours, dish sizes, free FTA program and paid-for encrypted programmes to watch.
