I've built two of the scratch build W6NL 40m Moxons. It performs as
Dave claims. It was not an inexpensive antenna to build given some of
the element parts. Probably about the same as buying a commercial 40
and modifying it. It weighed in under 100#. A full size 3L will weigh
2 to 3 times as much or more, so tower and rotator need to be a lot
beefier but may have the F/B you want.
However, I recently had a QSO with Dave and he said he has a re-design
in the works to use only the stock sizes of DX Engineering tubing. That
would save a lot, rather than searching around from distributors that
rarely stocked telescoping sizes, although I note that On Line Metals
now shows many telescoping wall sizes. DXE has a great selection of
diameters and wall thicknesses available at good prices. All of my
tubing came from them unless they didn't stock it.

Firstly, I would like to thank y'all for helpful comments. I do appreciate
different points-of-view.
On my previous email, I didn't mention I already have a Cushcraft 40-2CD on a
120 feet tall tower driven by an Yaesu G2800.
The idea of building a 40m full size yagi antenna called my attention, so did
the W6NL style moxon. May my 40-2CD be converted into a W6NL moxon style one.
Any ideas? Comments?
6061-T6 aluminum cannot be found in Brazil. If I choose to build either the
moxon on the full sized yagi, I will have to buy that kind of aluminum from an
American warehouse. Any that has good prices? Import tax and transport into
Brazil will add another 70% on the top of everything.
Front-to-back is quite important to me. There are several Argentinean stations
running high power. They all have very good antennas.
Narrow pattern is a wish but I have understood it comes with more elements
which leads to more money and weight.
So, once again, any comments or ideas? I'm all ears!
