The JK 402T sure looks a lot like a W6NL moxon conversion no?

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.
