DIRECTV AT&T DIRECTV 30 Tuner Reverse-Band Capable Satellite Multiswitch

If you hooked up 24 tuners does it have to be 12 on Swim one and 12 om Swim Two or can it be 15 on one and 9 on the other?

Is this one newst than the swm32?

Does this work with a dual lmb 19” dish?

I forget, can you use a satellite splitter for cable for cable splitter for satellite?
