do they make a add on for a dish 500 so i can pick up the 129 satellite. just wondering if that is possible. maybe like a clap on lnb or something to that nature?
Not really. The farther the satellites are separated in the sky, the farther offset the feedhorn must be in order to see it at all. This means (because of that offset) that the signal strenth is lower. This is why a slightly larger dish is needed. What you want is a 1000.2.
