The antenna is most decisive for the performance of an EME system. The radiated power is predominantly determined by the size and the make of the dish. The electrical pattern of the antenna as well determines the sensitivity during reception periods.
My 10m dish has an f/D of 0.5. The reflector is made of stainless steel mesh with a grid of 8x8mm.
The weight of the dish with the feed, the feedhold and the relevant cables is 820kg. There is no counterweight required.
The dish survived the hurricane 'Lothar' which hit Switzerland in december 1999. Some forests close to the dish site have been destroyed and many buildings desintegrated.
