When you ask Which Antenna.. My choice would be a Winegard Sensar IV with Sensar Pro for over the air reception.. However.. You want satellite.
Three answers:
With a SINGLE receiver and either DISHnetwork or DirecTV (not DirecHDTV) many "Dome" and "portable" antennas will work.. (some will work with multiple receivers on DirecTV, Mine will)
With DirecHDTV: you need an DirectHDTV dish.
With multiple receivers on DishNetwork, You need the proper Dish 1000.x Dish.
X depends on where you park.
The reason:
Direc uses one bird for Standard Def (old NTSC standard) 101W, for most all customers.. They use two more in a different frequency band for HDTV and the dome type antennas (this includes the portable domes) can not pick it up.
Dish Network uses 2 or 3 birds (one for HDTV 2 for SD) and dome/portable antennas usually see one satellite at a time.. So if you want to watch a show on say 119, and your "other" a show on 110,, NO JOY will be someones. But with the proper dish-1000, you see all 3 and domestic tranquility is assured.
What I use: A winegard Sensar II with Wingman and Sensar Pro.. More Over the air TV than I can watch, 2 DVR's suck it in and store it, they will let me watch in the "Other room" or download to the computer for long term storage or portable viewing elsewhere (Also accept up-stream from the computer) all those things that "ONLY ______ lets you do" I can do and more.. When I finish my next upgrade I'll be able to
Record 2 shows
Watch 2 shows (Given a 2nd person to watch the 2nd show) WHILE 2 shows are recording.
Record 2 shows, Plus record a 3nd show for immed viewing when finished watching a 4th show on a different TV. (one TV has a "Pause" feature. Not all that happy with it).
And all with free, no monthly fee, over the air TV.
Home was where I park it. but alas the.
