Just in case you are not aware, none of the dome style antennas can receive the DirecTV HD programming and may also not be able to receive any Network programming. You can use a DVR or Genie but all programming will be in SD.
With Dish you can get HD programming but since you can only "see" 1 of the 3 available satellites at a time using a DVR or more than one receiver is generally not recommended.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
