hello how many feet does a ku band fta dish need to be? my dishnetwork 100.2 is about 2 to 2 and a half feet is this 2 small? also it is possible to aim it differently and get fta? when I rtried my coolsat I found the free fta that dishnet had and noticed when a sithed person was telling me other sattlelites that some had varying signal strengths does this mean they are with in reach? Hank
