OK1KIR EME Team - 5.7 GHz, Our New System

The picture gallery shows our new system for 5.7 GHz. The first QSO was with IK2RTI on July 11th 2005. We made 100 CW and SSB QSO and even two JT4G QSOs until now (May 2010). The system currently consists of 4.5m solid dish f/D=0.42, square septum feed with circular transition & simple collar choke, transvertor 5.7 GHz/145 MHz (DB6NT design) in the dish focus point, 0.6dB WG LNA (DB6NT) and SSPA 65 W rf from 2x TIM5359-45SL (DL2AM design).
