My MFJ Moxon was built for 10 meter phone. See below for what I find on my MFJ 259B.
I found the specs in the MFJ installation manual were way off in my particular location.
I could fine tune the antenna to bring the point of resonance to 28.400.
Since I'm a one man installation team I figure its not worth the effort of climbing on/off the roof to adjust my antenna then come back in the shack to check the analyzer ect.
So far my Moxon works great. I'm also using a NTE U-105 rotor.

28.300 R=38, X=9, SWR of 1.3.1
28.400 R=42, X=8, SWR of 1.2.1
28.500 R=46, X=6, SWR of 1.1.1
28.600 R=47, X=6, SWR of 1.1.1
28.700 R=47, X=6, SWR of 1.1.1
28.800 R=46, X=8, SWR of 1.2.1

Just for fun I swept through CB on the Moxon.
26.965 R=35, X=64, SWR of 5.0.1
27.205 R=25, X=40, SWR of 4.4.1
27.405 R=22, X=25, SWR of 3.6.1
