[DX] TA32 update-more puzzling than ever

Got some good feedback on things to check. Thanks to
all those who responded. Here is the current
situation. I took apart the traps to clean them (they
were spotless inside) and to tighten the coil wires to
the trap cover-both of these ideas had been suggested.
Then got out the antenna analyzer and tried the
antenna sitting on the ground-looked fine, just like
yesterday. Put the antenna back up on the roof-in the
dark even, and checked it with the antenna
analyzer-looked great again. I am using a 3 foot
jumper coax piece between the yagi and the analyzer.
Unhooked this jumper and hooked up the coax to the
shack. Went to the shack and tried out the yagi-fine
SWR on 10, problems on 15 and 20 again. This was less
than 5 minutes from when I checked it with the
analyzer.
You may figure that the coax into the shack is
bad-which wouldn't account for the fine SWR on 10, and
the fact that it worked fine thursday with the MA5B.
So, I take the analyzer back up, hook up the jumper,
and now the SWR sucks on 15 meters-just like it did in
the shack
Any ideas? Is running 100 watts thru it somehow
messing it up on 15 meters-enough that the lower power
of the analyzer still gets bad readings then? I
thought that yesterday-but if I damaged it yesterday,
how do you explain the fine SWR this evening after
reinstalling it (before the shack test).
Any additional help would be appreciated!! It is
things like this that sometimes make me think I need
to take up a less stressful hobby, like bomb disposal.
