Todd,
Of course putting concrete inside a pipe will make it stronger, but not
by as much as you might think. Concrete is strong in compression and
has very little strength in tension. The pole is subjected to bending
stress and thus has tension on one side and compression on the other.

It definitely stiffens the pole, and prevents water from rusting it out from
the inside.
While I might use the stiffening effect to get a couple of extra feet out of
the ground, I wouldn't start downsizing your poles because you poured concrete
in them.
I think it would be fair to compare the

Fact, according to Jeff Randall of DPW. The concrete need only come a few
feet above ground level as that is the point the pole would bend.

1) When we use this option, we bring the PVC conduit into the Sonotube
below frost level.
2) We had a similar situation after consulting
Hi Rich;
1) I never had a problem with conduit and frost heave, but then again, I
haven't dug up all my work after 10 years either.
2) We did a mount exactly as you described, large slab with rebar into the rock
at 45s, and bolt the pole to j bolts in the concrete.
