Ok here is what I have so I need help with this.... I have a D12-300 receiver and I have a few questions..... Does this receiver power the LNB on a single LNB dish or do I have to use a inline power supply like whats on my SWM dish with my H22 receiver? What LNB and dish would work with this receiver? I really want a simple dish and maybe a single LNB for this one receiver.
