I would strongly recommend the JK402T over the XM-240. I know you asked
about the JK402; but the JK402T is a much better choice - just take a
look at the SWR curves of each antenna, and you will see that the JK402T
is much more broadbanded.
I replaced a working CC 40-2CD, which is electrically identical to the
XM-240, with a W6NL Moxon, which is very close to the JK402T.
One would not expect much difference, replacing a 2-element 40 meter
antenna on a 22' boom with another 2-element antenna on a 22' boom.
In my case it was NIGHT and DAY, a tremendous and noticeable
improvement. I attribute this to lower loss in the loading coils, and
better directivity per element due to longer length.
The broadbandedness of the Tee-style loading design is amazing, and my
AL-1200 amp requires little adjustment while covering all of the CW or
SSB portion of the band in a contest.
I would not hesitate to recommend the JK402T, based on the performance
and design. Others have commented positively on JK Antennas build
quality and mechanical sturdiness.
No, I do not own one.
