I am talking about the half power thingy with respect to a series circuit of
which a antenna is designed around. Reg politely made a separate thread on a
specific part of that thread which referred to impedance, presumably because
Q was being bandied about where he thought probably it was irelevant.
Am I wrong to think that because a different thread was not made
the impedance question and amplifiers was relavent and somebody was not
being destructive/impolite?
Now to your pont of what is the kicker...a normal dipole cannot receive
Class-C (non linear signals)"?
Having being told about this thing that somebody read somewhere,
where is it leading to? Seems like I entered a class on engineering
and after 5 minuites I am wondering what sort of professor I had that not
only just read books out loud for his money but thought it was O.K. to read
from a wood working book. Can't we assume that a antenna is a closed series
circuit containing only passive
items ? If you have in mind that we must we consider an antena as a Class
something or other amplifier when determining its impedance then I am
hopelessly lost in a thread that can only end up nasty like some others did
and drive some more people away
because somebody wanted to play games of obstruction with the intent to
annoy. Now I see that somebody decided to change this
thread heading instead of starting a new thread . Now we are talking about
RMS meters and how they can be used ? Are we talking digital or analogue,
hand held or otherwise, high enough accuracy to satisfy all ( Nah that is
asking to much) Well it is an antenna newsgroup so it must radiate ,
somebody read it in a book and assumes that all are unaware of it so he
wishes to describe it
so others can make sense of what he read and why he read it!

I am not pointing the finger at you Cecil, I have no idea who the culprit is
or what his intent is.

Art, I assume you know that Class-C amplifiers are not usually used
for SSB since they are not linear for SSB. The basic confusion is
between linear systems and non-linear systems. If the amplifying
device (singular) conducts over the entire 360 degrees of an RF cycle
and the output waveform is a reasonable copy of the input waveform,
then that device is said to be linear. If you have two amplifying devices
operating in anything except Class-A operation, the output of each
individual device is not linear. That's the kicker. The "two non-linear
device" option is not available at the antenna for receiving purposes.
A normal dipole cannot receive Class-C (non-linear) signals.
