Is there anything special I need to know about the DFW HD channels? Saturday I'm getting a Dish 6000 receiver with the OTA adapter installed, so I'll finally be diving into HD. I live in Wylie, which is in the NE part of the metroplex, basically just east of Plano. I have a south facing house with plenty of clearance to the south and hope to put the OTA antenna in the attic. I already have a Dish 500 system installed, so I don't think any real work needs to be done to that. What types of antennas have people had success with in DFW and how do you align them? I've been told the broadcast towers are all on one hill towards the south, but I don't know specifically where that is. Any advice I can get on this will be much appreciated.
