The DTV satellite (multiple satellites, really) it about 200 miles due south of texas. And I honestly can't remember the last times I lost reception. Oh wait, yeah, hurricane Allison. Then again, I get 98-99% on most transponders. I will say this: when setting up for the first time, using the signal meter can be a pain if you don't know which transponder you should be watching. Since they went to spot-beaming about 3 mos ago, some of the transponders will appear "dead" to you. They aren't, they just aren't pointing at you.
