Imitate or use something like this:

https://zcg.com.au/product/galvanised-steel-heavy-duty-parallel-extra-large-mount-clamp-boom-50-70mm-mast-115-185mm/
You can put it on the diagonal or fabricate flat plates for one side.
These are used by the dozen on our commercial towers.

A few minutes and few pieces of angle iron 1.5 or 2",x ~7" x 6 pieces and
you can build a far stronger and cheaper setup. No holes in the post. Then
2 u bolts in the angle iron to hold the mast.

I am planning to set up a BigIR with elevated radials. I have installed a
4
x 4 post in concrete and will use a Delrin rod for the EHU support. I am
having a difficult time finding a good 4 x 4 post to pipe (Delrin) bracket.
I would rather not just get long u-bolts and drill holes in the 4x4 post.
The following link looks to be exactly what I am looking for but is in the
UK.

Does anyone know of something similar in the US or have a better mouse trap
to attach a pole to a 4 x 4 post?
