I'm really confused, My dual lnb dish was pulling in a great signal but my single lnb wasn't getting nothing, so I hooked up my sat finder to get a signal on it by moving the dish. I still got nothing. I thought maybe the sat finder wasn't working so I tried one of my dual lnb's on the working dish to see if I would get a signal, which I should have got since it is already aimed good. I made sure I powered down the receiver every time I hooked it up. There was still no reading on the finder??? But now when I hooked the good sat back up , it gets the same reading as the single lnb dish which is just over 30 level and zero quality. I tried another 4-way switch but it made no difference. anybody any idea's? Thanks.
