I'm new to the forum and thinking through some basic questions on DBS capacity, especially related to the STA that AT&T has filed to drift their DirecTV-15 satellite to 101. It looks like DirecTV has gradually relied less on Ku capacity vs. Ka, but that DirecTV-15 has lots of Ku transponders (though this may be the last satellite with Ku capacity). Is it possible that they are drifting 15 to 101 to provide additional Ku capacity to existing dishes as they phase out satellites over the next year? Further, I have seen that most, if not all, newer dishes are HD only and that most HD content is delivered via Ka: does this mean that DirecTV will ultimately have fewer operational Ku dishes as they provide less SD service? Any thoughts or ideas are appreciated, I acknowledge that these are not sophisticated questions so apologize for the naivete in advance.
