I'm hoping to get HD signals into my H21, with a "SL3 SlimLine Four Out Ka/Ku LNB (SL3)". Alignment is the big challenge, and frequent activity (it's in an RV). With this SL3 going into the ASL-1, I plan to align using the ASL-1, powered by a PI-21, and then, using a "cheapie" signal meter ($20). I undestand I max the signal from the ASL-1 101 sat; then change to the ASL-1 119 sat, and max it. But does this LNB have a 119 output? I assume I need the BBC connected to the H21. I know the mast has to be perfectly plumb. I hate the thought of having to buy a $$$$$ Bluebird, etc.; and "dithering" seems stone-age to me. Soooo, anyone have some step-by-step cookbook procedures for this setup?
