you remember those big huge satellite dishes that the rich people on your block had in the eighties?
as far as i know the idea behind them was much like a concave mirror and the reciever thing was at the focal point, right?
but since they were mesh, presumably so that they wouldn't be weighed down by water or snow, wouldn't some of the signals gone right through the dish?
i don't get it, i'm sure my understand is just wrong.
