The installers had installed all of these splitters connected together. What I'll call #1 splitter is down from the antenna on the outside of the house at the 2nd floor to a 2nd floor converter box & TV. #2 splitter is in the basement connected to a digital converter box & TV. #3 splitter is on the 1st floor on the wire split that runs along the basement ceiling up to my 1st floor converter box & TV.

Since I am testing the "reflection" issue, I was going to get on the ladder and disconnect the #1 split off, and then disconnect the #2 split off, thereby testing the longest run of wire to the #3 connection and TV.

However for my test, can I simply disconnect any 2 of the splits at the converter/TV no matter where they are - this leaves what I (as a lay person) might call "non-terminated" antenna wire out there. This saves me from going up on the ladder for a test.
I have actually done this (that is, disconnected the wire from converter/TV#1 and from converter/TV#2 and it seemed to help a bit in a short test. I am not totally convinced that this is the answer until I see how it works over a couple more days of time.

Is this a valid test (with these, as I say, un-terminated cables hanging out there) or should I disconnect from the actual splitters themselves, leaving one long contiguous run (albeit with splitters as connectors in the long run) ?

Thanks again for all the input..
