Abstract

We summarize the main EMC-related design details of the Australian SKA Pathfinder (ASKAP) radio telescope dish antennas as now built at the Murchison Radio Astronomy Observatory (MRO). The sensitivity of ASKAP, and that proposed for the future Square Kilometre Array (SKA), demand that the dish antennas operate within a highly-regulated low-level radio frequency emission regime across a wide frequency range (0.05 GHz – 20 GHz). We discuss the key aspects of EMC concerns in the ASKAP dishes and some lessons for the SKA dish antennas.
