Test Configuration

As derived in this dipole drawing, an absolutepositioning for the measurements of -7.4 inches from the home position of the XY table corresponds to -0.12 inches on the CST reference frame.This position is derived by deploying a plumb bobto establish a reference plane tangent to the elements.The corresponding absolute position of the XY table is -9.4 inches.The CST reference is at the center of the ground plane or -1.88 inches from the tangent reference plane.ThisTable summarizes the phase center positions at different frequencies derived from CST simulations.The simulations are also with a stacked dipole and an offset position dipole added.

E Plane: CST Simulations vs Measured Data

• Center Dipole Only:Two measurements at each frequency where the dipole is flipped 180 degrees. This is to characterize the external range reflection.
