Well you are too far gone down memory lane, you are unable to focus for any
length of time and can't remember things or what you have said in the
past.No wonder you keep close to books, your memory has gone. Now go back to
your book and see that the high impedance comes from a parallel circuit with
lumped components to which radiation is not considered and there is no
length to the connections between them. It does not mean that a radiating
antenna which is in a parallel configuration will have a high impedance., It
can have a high impedance or even a low impedance and you must account for
distributed loads in any of your calculations to determine whether it will
be high or low when the bandpass array is resonant.
Now you probably will not find that statement in a book so you are in the
hole with no way of getting out. You just blew it and you are stuck with the
statements you made including the one that states that such an arrangement
violates all the laws of nature as well as remembering what post you are
responding to. Or is that deliberate because you found it embarrasing to
think of responding to it, as you have not got the ability to speak in
fractured English like Shakespeare which allows for a lot of wriggle room. I
leave it at that and maybe while you are still alive somebody will be kind
to you and explain that which you cannot comprehend or if you are still
around in a couple of years you may be able to read it for yourself when it
is in print. I didn't really expect that you could come up with anything of
detail, just words
Bye

My statement was: "A parallel resonant circuit is a high impedance (low
admittance)."

I reaffirm that statement. It assumes a high-quality circuit. It is
general and nonspecific. It is not all-inclusive. It allows exceptions.

In the ideal case, only perfect inductance and capacitance comprise the
circuit. Z = XL/R. As R goes to zero, Z goes to infinity.

The impedance of a parallel resonant circuit is:
Q(XL).
