Hi Bill
I had the same problem here.  This fall, I started checking
things out, and found the 20 meter monobander had a SWR of less
than 1.5 to 1 over the entire band.  Made me smile till I
remembered it never did that before.
I checked the feed line and there was a split where it had been
rubbing against the tower.  I peeled back some of the insulation
on the outside of the cable,and it was all black and cruddy.  I
replaced the feedline, and now the SWR is back to normal again. 
Sure was nice to have that flat response for a while :-).  Funny
thing was, it still seemed to work OK.  73
