Well sadly, not used any more. As you look out across Mexico it looks like some deep space tracking "area". Many of the houses had C or K band (I think) receivers for years as the only connection to civilization. In more recent times we're become modern and receive Dish (illegally) ShawChoice (Canadian) and Sky (Mexican). So, now there are all these huge old dishes on top of roofs all over the place with no purpose. The most creative use for them so far is to take them down, flip them over, put columns under them and use them as a support structure for a "palapa" which is a thatched roof over a bar, sitting area etc, actually works pretty well. The one on my casita is even larger.
The Dish situation is one of the many little "challenges" of living here. Apparently Dish hasn't paid off the proper people down here so it's not "legal" to have a receiver with a MX address, so, through many channels we have proxy address's, mine thinks it's in NYC and so I get all the NY news, weather (?), sports like the Hoboken Hasbeens etc. But, times change and so do we - eventually. Everything in Mexico is "manana" which doesn't mean tomorrow, it only means "not today".
Probably the single biggest nuisance here is getting anything hauled down here. Shipping anything of value in from the states through customs immediately costs 15% and runs the real potential of not appearing on the receiving end. So, we ship into the states and haul it down by personal "mule". Right now I'm considering shipping a webcam to Canada to be brought down by a neighbor who is currently there and returning soon. But, all that said, the "weather" is incomparable.
