what is it with all these customers who install their own directv and think that they can get away with using a cable splitter? or even worse, forgetting a multi-switch? "I just hooked up one LNB to one reciever, and the other LNB to the other..." Does the word professional installation mean anything to these people? Not that some installers are much better. I had one on the phone the other day, and this guy had no IDEA what a multi-switch was.
I should have asked him, "Sir, are you a licensed directv installer? Put the people there on the phone, please... Ma'am, this guy is a fake!" But I educated the 'installer'.
