John Kraus was also my mentor through his great book, "Antennas", Ed 1. John was
also a close friend of another of my mentors, and colleague, Dr. George H.
Brown. John credited Brown for originating the concept of increasing antenna
gain through close spacing of the elements, which resulted in the two-element
W8JK beam. Brown was ridiculed for suggesting such blasphemy, even by the US
Patent Office in rejecting his patent application. But it was JK who realized
its significance and applied it.

It is sad and unfortunate that such a great person has to leave us. Thus
endeth his great contributions.
