Lucky you to get such a pole for free!!! :D)
Use NO concrete! The pole will shrink a little over time
and there will be a crack to let water in and stay there,
accelerating the rotting of your pole! Concrete will also
prevent you from making below ground periodic inspections
per the reference suggested below.
Backfill with dirt or use some fine-graded sand that you "water in"
to fill all the voids.
BTW, there are Bell System Practices (call BPS's) that *may*
be posted on the web that describes the proper install, loading, etc
of wood poles. Google. If not, maybe a dedicated Telco ham
just might have a copy in his personal library!
I'd be tempted to rig the beam and mast with a "tilt-over" feature
using a small winch to make it a no-climb antenna structure. A
"cradle" would prevent side-to-side movement at the top.
Now back to my workbench. :D)
