I agree if you don't want them in your house, buy and install yourself. I know that when I got my 622 the tech put the 1000.2 up and I installed the 622 but that was just to save time, and I had alot of cables back there but they finished the install inside with me, and they were awesome (Best techs I have met doing a job) The first time ever calling one since they wouldn't just ship me the dish and receiver.
If you call them they will come, if you tell them not to come in they will leave, and you can stay with OTA.
