How high was the antenna when you checked it with the MFJ?  You can check
the continuity of the loading coils with an ohm meter. If you are using a
coax wound choke you can check that too with an ohm meter.

I put a new xm240 together (after a number of parts issues) and when testing
it with a mfj 259 it is resident at  2:7 to 1 at 5926.0 shows 10:1 anywhere
else tried 2 baluns and feed lines. Could this be a 259 issue although it is
a newer one (to replace my very old one) .Has anyone had trouble with the
traps/loading coils they use? First new antenna I have built in 40+ years
and it does not work, very frustrating as this is all just slide together
and measure. Any thoughts would be helpful
 Thanks
