OTA sharing same cable

[JosephB]

They are power-passing, see NAS STD-9501 Satellite / Off Air Diplexer Power Passing (STD-9501) | STD-9501 [DIRECTV] | STD-9501 quad combiner off-air combiner STD-9501
75-ohm resistor caps should be used on all open SWM lines and splitter ports, so I guess you would need to terminate the diplexer.. But why would you want to use a diplexer without using the sat port?

Just curious, I don't even have an OTA antenna at the moment, but thought I'd go ahead and throw that question out there

It works. I connected the amplified antenna output and the satellite output to a diplexer (with power passing) outside the house. I made no changes to the SWS-4 or power inserter inside the basement. I then attached a diplexer at each television. I didn't lose any of the satellite signal strength which is well into the 90s; however, most of the OTA channels are around 50%. I plan to make some adjustments to the antenna to help that.
