Why does my Kathrein UFS 641si say 'No or bad signal'?
- RRaymond LeeAug 6, 2025
If you're seeing a 'No or bad signal' warning on some or all channels on your Kathrein Receiver, the issue might be with the antenna signal or incorrect LNB frequencies. First, consult an antenna specialist to check and repair your satellite reception system if needed. Then, go to the 'Installation' menu and check the LNB configuration for the relevant satellite. Ensure the settings are: High L.O. '10.600' GHz, Low L.O. '9.750' GHz, and Limit frequency L.O. '11.700 MHz'. Adjust as necessary.
