[TowerTalk] Nube rebar question

[Kent Olsen <kilo6dko@gmail.com>]

I have never worked with rebar or concrete but it seem fairly strait
forward in building the cage and pouring the concrete. I have read the the
rebar cannot be with in 3" of the dirt or it will rust and fall apart. What
do you do in the bottom where the rebar sits on the dirt? Is this just a
sacrificial bit?

Thanks
