John,

The larger the diameter of the conductor the lower the frequency for the 
same length. It used to be called the K factor but I think they have a new 
name for it. Check any good antenna handbook for formulas etc. You can 
correct by trial and error, just folding back a few inches on either end and 
clamping with a split bolt.  Using a 3" diameter tube vs a #12 wire on a 40 
meter 1/4 wave vertical  can be the difference between 30 and 33 feet if I 
remember correctly.
73,
Ron W8RJL
