The geometry implemented in commercial electromagnetic software provides insight into the effects of the slanted beam-waveguide, shaped reflector illumination and mechanical tolerances, which are known to be more stringent compared to a perfect paraboloid. It is shown that the theoretical maximum gain and aperture efficiency at 5 GHz are 63.80 dBi and 85.45%, respectively. The corresponding values at 6.7 GHz are 66.47 dBi and 88.00%, respectively. Comparisons to sidelobe maps produced from astronomical observations are also discussed, showing possible misalignment in the structure when utilised outside its originally intended purpose.STAMPAenConference paper10.1088/1757-899X/321/1/0120032-s2.0-85045658138https://iopscience.iop.org/article/10.1088/1757-899X/321/1/0120032018MS&E..321a2003VFIS/05 - ASTRONOMIA E ASTROFISICA
