I feel sure that has been asked before but was not able to find on a search. I have upgraded to HD and the install is planned for early next week. I understand that I can expect the Slimline 5 LNB Dish an HR21 Receiver. My question is what is the maximum distance allowed from the Dish to the Receiver without amplification. The Dish install manual mentions runs that "far exceed 100 feet (150 feet or more)" but did not specify an upper limit the installers may use. The deal is that I have lots of tree close to my house but an unobstructed view from the lower part of my lot which would probably be about 150 feet after burial and routing to the receivers. Any help here would be greatly appreciated.
