Last fall I put a 6x6 post in the ground to serve as the support for a
Butternut HF2V that I had been using for several years (mounted to pipe, fence
post, etc over the years).
I used a terrific product (they call it a "Radio Support Block Clamp)
available from DX Engineering that secures the aluminum antenna to the 6x6 and
insulates it from the post. The antenna survived a pretty severe upstate New
York winter and is ready for its second winter upcoming. I used two of their
clamps to secure the Butternut vertical that is just about the height of your
1/4 wave 40 meter vertical. I can send you some photos of the installation if
you are interested.
I also used DX Engineering's stainless steel radial plate - and it worked
extremely well.
Here's a link to their site where you'll see the radial plate (their part
number DXE-RADP-1P) and their Radio Support Block Clamps:

This would eliminate your concerns about conductivity of the wood posts.

Subject: Topband: Insulating value of treated wood at RF
Hi All,
Looked in the archives and didn't see anything, which kinda surprised me. I
was going to cement in a treated 4x4 post and bolt my 1/4 wave 40mtr
vertical to the post and use one bolt as a hinge point to walk it up. I
began to wander about the insulating value of the treated wood, wet or dry,
at rf. Any info on this, or am I just concerned over nothing?
Thanks,
Tony
