From reading over at the swm8 site it looks like cable will be able to be used with SWM.

I think I have the wiring right but I wanted to get some more experienced people's opinions. The cable feed will go into the SWM8 on the Off air port. Out from the SWM1 port to the PI. From the PI to splitter out to the Digital cable box and to the HR-21 pro.

Will the cable pass through the PI? I know you have to use SWS-2 approved splitters, but will they pass the cable through as well?

Thank you so much

Install set for July 29, NFL Sunday Ticket... Can't wait!!!

It may or may not work.

It all depends on the band(s) your cable is using for its digital tier.

OTA signals (55MHz-698MHz) will not conflict with the SWM channels.

You might want to search this board...I think someone posted the frequency block used by the SWM.

As long as the digital cable QAM channels don't occupy the same ones, you're OK.

The squeeze will be on the cable TV company's return signal. SWMs are supposed to use special diplexers that rout the 2.3 MHz return signal to the DC/22KHz/950+Mhz port, but it is possible that in so-constructing a diplexer, that it roughs up the low end of the range that cable companies use for their return signal, which, in one market where I do a lot of work, is 10.5 MHz.

Mine was 20 MHz.
This is one of those YMMV things and only by trying it would someone know.
