140cm communications dish.
Discovery H-Line feed placed at same focal point location used when it was communications dish - ao it should work!
Test under way now to see if I can successfully pick up hydrogen.

When it was a comms dish, what freq was it at? I found for the solar cookers I had to adjust my focal position as a function of frequency.

I don’t know – I got it through a 3rd party so the link with anyone who might have answered that question was lost.

I'd suggest then you experiment with spacing like Alex P. Has done.
