I have tried POTY and Helix feeds so far and would like to try a Septum feed on my offset dish with f/D=0,6.
Has anyone tried such a feed for QO-100 yet? Those are widely used for 13 cm EME.
Would like to know your experiences, before I start the project.
Yes, I know it is only for TX and I need a seperate dish for RX - I just would use it for DATV uplink if it is better then the others.
