Years ago. The problem is that I could not get the pattern legal for the smaller antennas I built. I never built 6’ or larger dishes so legally 6 GHz was out for me.

Fairly simple, circular waveguide inside another larger tube. Waveguide mode in the 11 GHz and a form of coaxial mode for 6 GHz. Those old AT&T cornucopia horns would do all frequencies. Basically just larger and larger waveguide with the lower frequencies injected at the larger parts of the waveguide. Took lots of physical space for the combiner but it was pretty cool. I would have enjoyed designing them back in the 1950s.
