I have a good view of like 15w to 61w in the yard and need to get a circular dish setup to get some of these. I want to start out by getting 40.5w and 22w. The available channels list circular settings. I have a 6 foot dish with a circular dmx242. Is there any particular skew requirement when setting up a circular lnb like this? I am also looking for a circular lnb that will bolt up to the standard 4 bolt feedhorns. If this 6 foot dish won't get the signals I will get them with the bigger dish. I want all of the Atlantic channels possible. I am also negotiating a new 7.5 footer radio shack dish that I hope to be picking up by spring.
