Connecting a New Raven Quab LNB to original Sky dish I recently brought a Raven Quad LNB on E-Bay with no instructions. I want to use this with an extra Sky box and FTA card I have. I tried to replace the original single LNB with the Raven one. The Sky box said "No Signal Received" with the Raven LNB connected and with 2 cables attached. However, the Grundig single LNB works prefectly after trying the Raven LNB. I have the proper cable and F-connectors attached. I checked the setting with the secret menu on the Sky box and reset to default settings. Everything checks out. Has anyone any experience installing these Raven LNB and can anyone assist me with the above ? P.S. What do the numbers 1 to 5 (dial ?) on the front side of the LNB do exactly ? Any help would be appreciated !
