Properly designed, they have a good reputation for doing what the
theory says they will do. Just remember, though, that you're going to
have to sewer almost half your transmitted power into the terminating
resistor. But that's the half that would be going the wrong way,
basically.

But it would get there - eventually Long or short path. But I don't
know if both paths are ever open at the same time to the same extent. If
not, then it may not be a problem. What about running a transmission
line from where the terminating R would be, back to the feed point?
Assuming you can match it all that is.
