How does the type of dish you have affect satellite reception?
Answer:
It depends on what you're watching. If you're watching international channels, most likely your 30" is what you need (or a Superdish if you want to spend more).
If you're not watching international stuff, use another LNB or get a Dish-dish with multiple LNB's if you need them (to receive multiple satellites/more channels).
BTW, 30"'s get great reception..but are more prone to movement due to wind (depending on how it's installed/mounted).
It depends on if the dish is a Ku band type dish and you can find that out by looking at the LNB at the end where the cable hooks up. With dish using 2 sateliites for programming I would just get one of the 20" eliptical dishes and be done with it.
