Waves induce current into an antenna. Any mismatched antenna reradiates
most of the energy induced into it. A perfectly matched antnna only
reradiates 50% of the energy it receives.

Richard,
Some time ago I stated that a yagi antenna operated under a
mathematical binomial function. This was termed as junk science in
this group which raises the question again as where does the energy
that is not reradiated go ?

" A perfectly matched antenna only reradiates 50 % of the energy that
it receives"

This also suggests that an array without parasitics required for
reradiation is a lot more efficient than an antenna with parasitics.
Seems like this group is going around in circles unless this 50% finds
a way to radiate in some alternative way !
Is the 'perfectly matched' statement of any importance that demands
it's inclusion with respect to re-radiation efficiency of an antenna?
Regards
Art
