Picking the "best" 40m beam is very hard on 40m and requires a
compromise unless you have a big tower, a big rotor, moderate wind/ice
exposure, height limitations and CW/SSB only vs. wideband CW+SSB. Oh,
and a serious budget of course. That's why there are so many different
designs in the market.
A bit of the decision process for both the beam type selection and
suppler may be found here for those interested:

Momobeam makes a T element 40m beam also, I used one last year operating as
PJ4R. I have modeled a lot of 40m beams and it is hard to get a lot of gain
with a single antenna. The Moxon is a nice design but it does not defy
physics.

All true, Jim.
As well, re W6NL's design of the 40m Moxon being discussed. I built/own
two. Also NEC4 verified. K3LR and 8P5A use them. The JK Moxon looks
like a close derivative.
