[TenTec] OT: Antenna Problem

[K5XS at aol.com]

Off topic, but I figured among my Ten TEc friends there might be some  
expertise.
 
Suddenly my SWR on all three bands has jumped significantly on my Cushcraft  
A3S tri-bander.  It's up to 3:1 on 20 and similarly high readings on the  
other bands.
 
I'm scratching my noggin (and trying to avoid thinking about lowering  it).  
Would it be a trap if the jump came on all bands?  Might it be a  feedline 
issue?
 
It happened rather quickly, which leads me to think it is a trap failure  
(ugh), but I wonder if that would manifest itself on all bands.
 
(Fortunately, my new Orion II has a nifty tuner, so I am surviving.)
 
Thanks for any advice.
