I have a Dish network VIP 622 HD receiver and the distance to the dish is about 60-70 ft. When the receiver was installed dish initially said that this might to far away for the system to work but after some signal tests they said that everything was within minimum signal strength for it to work. My problem is that not all HD channels work or work intermittently. Some work all the time, others are intermittent and about many I have never been able to see. The channels that do not work say "The satellite signal has been lost. Signal acquisition is in progress. Please wait" Signal strength on the receiver is normally around 71 and "check switch" shows everything in green/OK and status as "good" I did some googling and see some suggestions about installing in line amplifiers to fix this or replacing splitters with better quality ones. If an in line amp will work do you have an recomendations and where do you install it. Placing an inline mid way between the dish and the receiver is not an option as the cable is burried under the ground! Does anyone have any suggestions to get this resolved?
