I second that...are there 4 holes in the feed horn substitute (only 3 visible in the photo)...and do they allow signal entry to the waveguide from 4 directions ?
Or are the holes simply for mounting ?
Yep ..as I first thought then ..I second that.
It's a waveguide that allows the signal path from four offset dishes to combine in the same feedhorn.
I can only speculate that there could be a cost benefit, otherwise why not get a larger dish?
From the little I know yes you would need more than two holes to monitor radiation patterns,Yep side lobes occurred to me too ...(ties in with my first guess) ...but would you use 4 holes as entry points ?
2 would suffice I think..
