I recently installed a new Bencher Skyhawk 3x10 tribander and experienced
nearly the same type of SWRs... only mine were actually worse in some

Turns out that the culprit was a bad length of coax!  Replaced it with
Davis RFs BuryFlex and the world is again safe for mankind...!

If you have not done so, have your ant guy take one of the MFJ-259
Analyzers (surely you can find one to borrow for a short while if 
you don't own one), up TO the top of the tower and check the SWR
AT the feedpoint of the yagi.  If it's good there, then suspect
your coax.
