No, there will be no downtilt or uptilt with a corporate-fed stacked dipole antenna. The main lobe may become fatter, and sidelobes may increase, but their elevations remain the same. Jeff's earlier post explained it very clearly. Kris, I believe that your findings are a result of having real ground under an antenna, in which case you'll find similar data no matter what kind of antenna you model. Laryn K8TVZ
