One thing to try would be some random lengths of coax extensions from the normal point you'd measure the reflected power.  You might be "lucky" and be at the right spot in coaxial length to not even see reflected as its being eaten up in the feed line that's close to resonance. Have you driven the path to make sure

Actually, the system *hasn't* been working, at least not as it should. Remember, in my post I said that the signal strength has been about 300 uv ever since I started recording it when I got here in 2005. I think what caused my recent dropouts was a couple of incidents of temperature inversion that occurred when a severe weather front moved through.

Yes I understand the "coax length" phenomenon, and if necessary I will run further tests on the coax.
