Abstract : Previous work on this contract produced a method for predicting the far-field pattern in the horizontal plane of a thin vertical antenna in the presence of conducting cylinders of arbitrary cross-section. However, this technique appeared to be valid only if the scatterer was taller than the antenna. This memorandum discusses an extensive set of measurements that show the influence of the scatterer to antenna height ratio on the far-field pattern, and also how the actual antenna height itself influences what this ratio should be. Thus, the limits of validity for representing finite height configurations with infinitely tall ones are now more closely defined.
