Don't make up a false augument, nowhere do I say that parts of a dipole

regarding something I didn't say. As for your parlying the term 'false' so
liberaly it is clear that you were sleeping during class, but then even
those who know little of radiation can have an oponion.
So what is your vision of the future with respect to antenna and are you
doing anything to make that vision come true i.e. walking the walk.or are
your jollies gained by shooting at those such as Cecil that does have the
required knoweledge? On top of all that read carefully regarding'
efficiency' since I have qualified it as ' per unit length'
Best regards

Actually, Art, I have come up with a small antenna that radiates well enough,

although I don't see any point in making anything out of it since I can't get
it
to do anything impossible. ( A full-size antenna would work better.)
I apologize if I misunderstood you. You might pause to consider, however,
that a half-wave dipole at the correct height is quite efficient, anyway, and
improving it from, say, 98% to 99% won't gain you much advantage,
even if your idea has merit.

Art said, in part;

"It is well known that the ends of a 1/2 wave dipole can be
lopped off without any noticable difference which can be seen by
the area lost under the normal current flow diagrams, so
efficiency can immediatly improved."

You are right, you didn't say that the ends of a dipole do
not
radiate. But, by the above quote, you have implied just the
opposite.

PS - Peashooter is back on the rack again.

Piddle means to mess around with things

So does that mean an experimenter attaching an antenna to his chimney is
a piddler on the roof?

What low efficiency portions?

He may well be correct if we are all lemmings but
people who piddle with antennas are a different breed.
Personaly I see antennas gyrating towards smaller
antennas where radiation per unit length will finish
at the top of the heap
Antenna engineers have become so focussed on the half
wave patterns that they have completely ignored the
low efficiency portions at the ends of a half wave
antenna. Future antennas most surely will remove these
low efficient radiator parts together with the addition
of coupling techniques that will help to move away
from the Yagi syndrome, together with resolving the
of a "lossless" coupling direct to the transmitter
that will obsolete the need of matching interface.
Ofcourse this is where my intersts lie, but does this
vision of the future match yours or am I thinking
of the impossible? One noted Russion scientist stated
that theoretically radiation can come from a single point,
is this part of our future or just an impossible dream ?

ten seconds of cheap glory.

Probably because you passed up four technical questions:
could you provide more detail?
What is "Yagi syndrome"
lossless coupling to the transmitter?
What low efficiency portions?
to indulge yourself asking this.

For goodness sake why don't you and Danny put away your pea shooters and
handle yourselves in an orderly manner. I have not avoided or passed up any
questions, I am just in a standby mode to see what others visualise
as what the future might bring or what they would like to see ,after which I
will elaborate on my thoughts even tho
some lurkers such as yourself may well be concentrating on distance and
accuracy of their pea shooters.

Richard,
My peashooter is racked. Guess that means I'm just
