EMC techniques for a complex project: Karoo Array Telescope

The Square Kilometre Array (SKA) is to be the most sensitive radio astronomy receiver ever constructed. The Karoo Array Telescope (KAT) region, part of an SKA bidding site in South Africa, has been proclaimed a radio quiet zone. This paper describes several contributions our group has made to the strategies used in the management of environmental RFI and self-generated emissions. Additionally, we are interested in the hardening of telescopes against lightning.
