Need help and can't find any good answers. Just purchased a Slimline 5 LNB with 4 outputs and a HR21-100 receiver. We ran ONE line out of the Slimline 5 LNB into the back of the HR21-100 and couldn't get any type of signal. The dish is aligned according to our area. It looks as though we might need a power inverter or a multiswitch or both. Directions that came are worthless and we are getting conflicting directions on the internet. Should we be running four lines to multiswitch and power inverter? Is it bad to hope he falls off the roof???
