Okay, ya made me look.
On Lyngsat, it looks like there is FTA programming and beam coverage for the sats at 137°w and 139w.
You would have to confirm coverage and interesting programming.
The idea of course, would be to use your existing big Ku dish aimed at 129°w.
Not offering any ideas as to how to mount outrigger LNBFs, though.
There is also a global-coverage beam on the 177°w bird, but nobody cares.
Lyngsat links to coverage maps; those are what I used.
Didn't know what elevation you were shooting 129°, so I didn't look at any birds east of it.
