Dear islam,As the LO low

Dear islam,

As the LO low frequency and the LO high frequency you have mentioned those are the default , i tried those even except the band selection in your setting is auto but i specifically i mentioned as a high but no channels.

 For high frequencies i am applying the attached setting and they are receiving proper channels,somebody told me always keep these setting and you will get the channels.

actually i dont know what is exactly LO low frequency and LO high frequency can you elaborate more on this i want to understand what actual role these setting plays

 

Thanks

Hi Can you enable bias

Hi

 

Can you enable bias "enable"?. Let the frequencies as default , and follow the attached , apply config , then reload. After that you should get channels. Kindly be informed the attached config from success stories .

Hi i am so sorry for the

Hi

 

i am so sorry for the delay . Kindly find the below :-

universal LNB has two positions by default which are 9700 & 10600 "already written on LNP" these two values ok for all Nilesat , Arabsat , etc.. .LNB fixed on satellite Dish and installed normally on outdoors , the signal needs to pass indoor using cables.The job of LNB is to take block of frequencies , amplify and convert them to similar signal.Frequency range is 950MHZ for Lo freq , and 2150 MHZ for high freq , because all coaxial cables has impedance 75 ohms , and their a loss of signal on lo freq 950 MHZ , high freq at 2150.On DCM
Lo freq (950+) , High freq (2150+)  these values to correct the loss which will happen on coaxial cables. All recommendation do not change the default settings for LNC setting , because you will get loss for frequencies.So when you change the Lo , or High value this should meet the LNB values .

 

Thanks
