The RCA TVPRAMP1R does have dual inputs and is inexpensive. It seems to do well; I'm using one with a GE 34792 Attic Indoor antenna.

There are reports about QC problems, in particular about the combined/separate switch not making good contact with the VHF antenna with the switch in the separate position. The fix is to set the switch to combined and use a UVSJ, which brings you back to where you started.

There is also a review by an installer (Robert Hughes) on Amazon who likes the RCA preamp, and has bought many of them as Amazon Warehouse Deals. The power inserters have a high DOA rate, probably because they were returns that were never tested.

I'm seeing a similar pattern with Duracell batteries on Amazon. Amazon is shipping them in plain packaging instead of the original packaging; many batteries are old, DOA, or leaking.

I suggest you try the RCA preamp, but order from Walmart instead of Amazon.

I'm still confident about the AD and RS UVSJs, but not the MCM. Maybe I'll make some tests of the MCM to see how it compares with your results.
