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?

It’s 15 tuners on each swim. They are separated and don’t cross communicate ( recordings on a dvr on SWIM one won’t show up on a set top box on SWIM 2.

Is this one newst than the swm32?

Yes it’s a Swm 30 but right now you are only allowed to connect 26 tuners to it per Directv and it cost about 45 dollars compared to 500 for the 32

Does this work with a dual lmb 19” dish?

Only for the 101 satellite and it would require two lines for both polarities

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

This question was posted on a 39 tuner swim module. Just to be clear, this item is NOT considered a splitter. A green label Directv splitter can be used as a cable splitter, BUT a cable splitter will not work a a satellite splitter UNLESS it’s rated for 2200 MHz (2.2 GHz). Green label Directv splitters also have a power pass through port that is sometimes used to power up a SWM module or SWM LNB. Some cable splitters have powere pass through ports and others do not.
