I have seen on James Long's site that several cities including Austin have two HD spot beams. Most but not all are from both the 129 and 61.5 locations. That certainly makes it easier for installations where LOS may be a problem but I doubt that is the primary reason given how stingy DISH seems to be with their bandwidth. Did these cities first have only one HD spot beam and then when the second was added it would have required going back and replacing too many dishes?
