Okay, newbie here, first post, I have been reading and reading....so here goes, and be gentle... Currently have Direct TV HD in Ohio. 2 HD DVR, 2 HD receivers HR-20, 3 sd receivers. I have a cabin a friend and I share in Ohio and I am transitioning to Arizona over the next year. I want to install an HD dish at the cabin and in Arizona. Today I ordered a dish, Kaku Slim Line Satellite Dish 99 101 103 Hdtv 3 LNB by DIRECTV, Technical Details, SL3 Slim Line Dish receives satellites 99, 101 and 103 Gets all HD channels broadcast by DirecTV Runs 4 receivers in all 1080P or P. Dish size: 22.5 in. x 32.5 in DIRECTV 3 LNB Ka/Ku SlimLine Dish Antenna for MPEG-4 C HD Programming. Cut and paste from a popular website on the dish info...... Is this a single line dish? Do I need a multiswitch for 4 TV's? 6 Tv's? Do I need a power inserter for each receiver? Can I integrate an off air HD antenna easily into this setup? (multiswitch? Diplexer? other?) Should my HR-20's work with this? What about my old SD receivers? Okay, first will this dish work for me? I don't need international programing, basically sports, MLB EI, NFL ST, ESPN gameplan and RSN. I know I can't get my locals in AZ, but at the cabin probably. I think all I need 99, 101 and 103 sats, right? I understand during the install, mast plumb, plumb, plumb.... Then tune in SAT 101 perfectly with elevation and azimuth. Then don't screw with elevation and azimuth. Use the tilt to tune in 99 and 103, very small adjustments at time and let the signal catch up. Which SAT tuned in second 99? or 103? Third? Are there better transponders to use on each SAT in Ohio? Arizona? I plan on setting myself, a receiver and a TV right next to the dish during the install and watching the transponders on the screen myself as I adjust the dish. Does anyone have any good links to instructions on the web, this site, other sites or videos? I am sorry I have asked so many questions, but I want to do this right and I have tried to research as much as I can. Thanks in advance!
