Tax I don't have this special LNB for get 118.8W, but, youcan delete the satellite in channel with garbage can in down menu exit and save, now do a blind scan with LNB Type: Universal, LNB High: 10750, LNB Low: 10600 return in antenna setup, be sure the setting is right then do a autoscan.
Note that: on viewsat if you delete the satellite you delete only the channels. Viewsat do not keep its setting in antenna setting after deleting the satellite.
