The ground you put in the concrete i.e. the rebar would not be optimum.
Concrete is a very good insulator. The common 8' copper clad steel grd =
rod
is hard to beat. "The more the merry" .  also single point ground =
system.
Try to get the neutral in your panel box at near the same potential. =
Plug a
one wire connector to the ground connector of a outlet an connect it to =
your
station ground wire. You do not want different potentials during a =
lightning
strike.  Imagine you were standing five feet from a tree that is about =
to
get a direct lightning hit. If you had your feet 20 or thirty inches =
apart
the voltage at you left foot would or might be 100,000 volts as the =
current
dissipates the father it gets from the tree your right foot may have a
potential of 30,000 volts the difference is 70,000 volts  that would =
blow
thru a pair of nike tennis shoes and you with not much problem. If your
station is plugged into a grounded outlet that runs 100' to your service
entrance and you have a separate ground rod out your window and a 10' =
wire
there will be difference in potentials .  REMEMBER SINGLE POINT GROUND
