Topband: Insulating value of treated wood at RF

[W. E. Bailey]

Tony

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.

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
