So I got a question for you guys. We are setting up a new 75E dish On an existing account. We have the skill and elevation set to working settings from other accounts in the area. We hooked up a receiver from a working account to our system and cannot get a valid signal. When we disconnected CO ax cable the signal meter continues to show a fluctuating signal which does not make any sense to me. We get the same results from receivers that are tied to the account that we are setting up. Any ideas
