Yes, I see that Cecil, but I suspect he is not a ham
and thus would not know the difference between
different arrays. But if he is really looking for "Aliens"
he may well be looking in the right direction but his LED's
have a skewed correct "reflector".
With respect to your two element example you stated that
they were both driven. When coupled correctly it is only
necessary to feed one element in an array and allow the
coupled element to be of similar phase and if possible
of a higher current flow to give you that 3 db additive
advantage . Plus single digit elevation angle for max gain
even tho the array is fed at 1 WL height.( 20 metres)
I could send you actual model details if it is of interest.
Or a photo if that interests you more.

I wonder who was the first to assign these terms
Or was it a poor translation from Japanese ( Uda and Yagi) ?

Please note that John didn't mention Yagi's. He only
mentioned "beams". :-)
