I'm seeing a lot of you use a dish 500 instead of a 300 for a add on or wing dish to get a extra sat. is it because of the reflector size or the dp system? I'm getting a dish1000+ in-spite of the outcry's from others i don't need it. and need to add an additional dish to get 148 or 61.5. is a 500 better for me in that situation? thanks! I'm here only to learn and not to fight, hassle, molest, pester, bother, or annoy anyone.
