Thank you very much for your helpful comments and advice. It looks like I will have to go without the
HD channels for now. You are right elgemcdlf, the
installer is a DTV installer. The reason why I wanted to have somebody install is that I have tall tree behind my backyard and have to put the dish on the roof of my house to be able to get a signal. I do not have a tall ladder and do not want to climb to the roof

. Now, I have another question for you expert folks. What is the best LNBF that you can get presently. I saw one with 0.4 dB noise is this a good one or should I select another one. Thanks again for your help.
