RX performance of home QTH system with 2,4m Prodelin offset solid dish

SN/CS = 7,7dB     MN/CS = 0,77dB

New offset dish Channelmaster 2,4m for 10 - 24 - 47 - 76 GHz EME

Feeds for 47 GHz in 2,4m offset dish

Complicated process of producing feed horn W2IMU for F/D 0,8 Right now scaled W2IMU feed and working on two of them for testing.

RX/TX switch

will publish here all details soon. Wave guide made by Pasternak MW cost 10.000 $ and have almost 0,5dB ATT with associated waveguides etc.. I have 200 $ solution and 0dB ATT.
