Not a reasonable answer, could be speculation like some of the comments
I get from experts. The yagi is not totally efficient in changing the
time changing field to a radiative field
because it has detuned elements contrary to what Roy states that a
reflector aids the forward lobe.......that is trash talk but many of
the so called experts are following like lemmons

There again maybe it is best that you be honest and say
you don't understand! Better that than join those who have
nothing to say about antennas!


Actually Art, you are already the master of misunderstanding.

See Tom you had nothing of value to say about antennas or the question
at hand
I think you would be better conversing with members of this group who
are intent on disruption and stop questions on antennas. What goes
around comes around so I will not answer in kind. If you want to stick
with the idea that a yagi is the next thing to sliced bread then be my
guest Better still study up on the code so you can join friends.


And to continue the theme -

Actually Art, yagis are usually better than 95% efficient.
