But I'd say not with the same advantages and convenience of the virtually single slot Ka/Ku dual band system as DianaC points out.
In addition to not needing to resort to things like down-rezzing full HD programs to 1440 x 1080 to allow more channels to fit into the smaller 24 MHz wide transponders on Ku band as dish does.
See now I think thats more Charlies cost saving measure more than a KU disadvantage. But when you haven't added many customers in the past 5 years you tend to not have a lot of money for expansion.
And when you get sued and lose to TiVo lawsuits that tends to take some out of the pot.
And remember Dish could have spent their money all on Western arc, If the Northeast coast states could have used the 129.
I don't think Directv would have had any of these issue had they went KU for everything.
