Topband: Radials help

Au contraire.

We HAVE been building.  What is different now is that we have affordable
tools that Mssrs. Brown, Lewis and Epstein would surely drool over.  The
photographs in the study and some other related literature outline the
difficulties they went through to produce the document.  What we also have
is the ability now to measure relative skywave signals (Remote Beacon
Network) in a way that allows real statistical  comparisons of stations in
many different propagation situations and locations, and get it down to an
accuracy of a dB or two, even for trans-oceanic paths.

Now the old topic is popping up with NEW designs to test out, and it turns
out there are some new things to compare.

BL&E had MONEY behind them, though they did have a wire budget they
exhausted (113 radials instead of 120, the story is they ran out of wire).
 For BL&E to have been truly comprehensive, they would have needed to redo
it in Hawaii, North Carolina, and a half dozen other places, to add another
matrix dimension to their figures in places with altogether different soil
qualities.

For our part, we just need to keep after the subject.  People ARE putting
up new designs on Top Band, and using them, and this annoyingly (for some)
repetitive topic has been the vector for the new ideas.

73, Guy.
