Hello, Roy and all. While I aggree with the above I think one has to keep
in mind that 50 years ago there weren't software MoM (e.g. NEC) and FDTD
tools around to implement calculations that don't lend themselves to
pencil-and-paper calculation. As a result back then there was
considerable "art" (I would call it engineering) involved in antenna
design. Hams, too, were coming up with many practical designs back then
as well as now. Practical experience was important then and still is.

Your points are well taken here.

However, I do believe there is a lot of "art" involved. We don't even
know what our signals are really composed of. We don't even really know
how propagation and movement of our signals takes place though the
medium which transports them; And, indeed, we don't even know the
medium through which they travel ... if not for brilliant and "artful"
men, this never would have occurred.

If this all does not make men stand in awe and wonder of these artistic
accomplishment and beauty of engineering achievements, I just don't know
what would!

Our imaginations have allowed us to reach out and use powers far beyond
the horizons of our vision. Sometime in the future, we will even refine
all of this ... as our vision(s) become clearer.

Warm regards,
JS

Science is the use of known laws to determine fault or to pursue a
predefined result.
Art is to follow intuitive ideas in the hope of producing an
acceptable result

Point well taken ... Einstein seemed to have a real "art" of predicting
which areas would bear fruit, and a path to follow to deduce their inner
workings.
