Prove I erred!

Put a sine wave in an antenna and you get a sine wave out.

Kraus says:
"The currents on the transmission line flow out on the antenna and end
there, but the fields associated with them keep on going."

Art in a previous posting said I should quote "Lady Chatterley`s Lover"
as people were tiring of Terman. I read it before it was even printed in
the U.K. (1960) but this is an antenna newsgroup and Terman is more
appropriate.

If people want something other than Terman, he gives a terrific
bibliography at the bottom of page 864 in his 1955 opus.

Art also said in a previous posting that Terman did not credit Maxwell
with defining radiation. Let me put the lie to that. On page 864 of his
1955 opus, Terman writes:
"The laws governing such radiation are obtained by using Maxwell`s
equations to express the fields associated with the wire; when this is
done there is found to be a component, termed the radiated field having
a strength that varies inversely with the distance."
