Re: [amsat-bb] Radio Lens

For further information about the SKA and some interesting papers on 
antenna selection see

I recall occasionally using an HF Luneburg lens in Hawaii for shore to ship 
and shore to aircraft (ARIA) links during the early Apollo days on the 
Western Test Range.  It was a wire antenna and had the main characteristic 
of being quite immune to signals off azimuth.  However it's not clear to me 
it was the same concept as the antennas referenced in these articles and 
papers.  I haven't found any references on the web to HF lens antennas 
which would verify that.
