Well Dish500s are getting out more than the ParaTodos equipment, elliptical dishes. But you cant say that all those subscribers are taking Dish Latino programming package.
They maybe just taking AT100 with locals, Univision, Galavision, HITN, spanish audio, local Telefutura/Telemundo affiliate if those exist.
Remember, Dish500s is "standard" equipment at Dish now. The elliptical dish is not "standard" equipment for DirecTV subs but is special equipment for DirecTV subs. For Dish subs, The StarBand dish is considered special, and so is using a second dish for 61.5/148 programming.
In Camden NJ, a very pooor city, I do see both Dish Network and DirecTV dishes. I see dishes everywhere (poor areas, rich areas in NJ and Philly burbs) but its not that widespread either areas. I havent seen a row of homes all with dishes, but I'm sure in rural America you'll see that.
Reception of TV signals is pretty good (no significant terrain issues), and many homes just rely on antenna and broadcast stations. I see more antennas than dishes.
