John, do not allow yourself be led astray by the waffle on this
newsgroup of the importance of supposed antenna gains and the
differences between one exaggerated radiation pattern and another.

Real professsional radio engineers (who are extremely few and far
between) who, to make an honest living, are obliged to work in the
real world, and are accustomed to dealing with radio-path propagation
uncertaintainties of plus or minus 10, 15 or even 20 dB.

But perhaps you already find enough amusement with such silly
back-to-front ratios as 50 dB and this little warning is unnecessary.
I'm sure it is.
