When we tested flight-1 at Loral, the downlink (2.492 GHz)being under high power was very tempermental, with a liquid cooling system that was difficult to monitor at the proto-type level with the hoses & pumps and temperature monitors. The antenna array had 96 patch radiators each backed up with a 5 watt amplifier (480 watts). It made testing a challenge because of 1) the RF power levels were high & a lot of heat was generated & 2) 2.492 GHz is right at the frequency that our Microwave ovens operate at. So I personally had some safety concerns. Also it was very easy to make a mistake and break something.
