Please help. I just had a new install done. Installer used a dual Legacy lnbf on a new install and he put in a 322 & 311 rec. He can't get them to work, he says the 322 has a bad switch in the back of the receiver, does this sound right? Also the cable he used is the skinniest RG6 I have ever seen, the cable doesn't have any writting on it so how can I tell if it is RG6? Thanks
