What is the minimum size of dish required to receive RADARSAT-2 data?
MDA recommends a minimum antenna system G/T of 29 dB/K to receive the RADARSAT-2 downlink. This typically corresponds to an antenna size of about 5 m or greater, depending on the antenna manufacturer. The actual required size will depend on the performance of the antenna system, the presence of a radome, the typical weather conditions, minimum required antenna elevation, and required link margins. RADARSAT-2 is also able to support smaller antenna systems with a system G/T of 26 dB/K (potentially as small as 3.6 m). In this case, only single channel downlink is possible.
