O.K. Reg
I'll take you up on the 50 db F/B.
There are old wives tales and then there are old wives
who just tell tales about other old wives.Which is it?
I have never read anything definitive about max F/B figures attainable.
I have heard unsubstantiated stories about narrow voids filling up between
lobes
but no data to back it up so I would call that an old wives tale.
There are computor programs that show large F/B figures, shall we throw
those away together with your programs as computor programs are all suspect?
Actually I have not seen any measured data regarding F/B radiation with
respect to
lobe angles possibly because of difficulties with respect to measuring And
also
what height the antenna must be before lobe shapes stablises.?
Now you have come forward and stated, presumably by experience,
mathematics or what ever, that 50 db F/B is silly. Why so?
What F/B figure is not silly and why, plus what are the parameters
involved that make this F/B not silly? Does this F/B relate to all antennas,
yagi's, dish forms, verticals, wire arrangements or what?
I am so pleased somebody has all this data so as to really substantiate,
without doubt, that it really IS an old wives tale ,or is it somebody just
exercising
their right to free speech regardless of content.
I await your reply with interest, and ofcourse, the scientific data that
substantiate
what IS an old wives tale and what IS not, and........ without "waffle"

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.

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.
