This site http://www.frontiernet.net/~jadale/Loop.htm states that: "A

Hello, and a loop (dipole) antenna doesn't "respond" to just the
magnetic
(electric) component of a propagating electromagnetic wave. A
(receiving)
loop or dipole antenna intercepts the incoming electromagnetic (EM)
wave.
Last time I checked an EM wave had both electric and magnetic
components.
Just because an orientation of an axis of the antenna resulting in
maximum
signal strength is parallel to the electric or magnetic component of
an EM
wave doesn't mean that it's responding to just that component.

I wish hams and others would quit trying to redefine electromagnetic
theory. Hams have designed and constructed novel and practical antennas
over the years but their explanations about how they work are often just
plain wrong. Sincerely, and 73s from N4GGO,


The explanations are wrong because the radio waves are simply the
electric
waves or the electron waves.


Hello, and they are most certainly not "electric" waves. What part of
"electromagnetic" don't you understand? (It's just this kind of stuff
that prompted my previous post) I take it you're not an EE or have ever
taken any undergrad/grad courses in EM theory. In any event someone else
can continue this starting-to-drift off topic thread. Sincerely,


He is either an idiot, an ignorant guy that refuses to learn, or a troll.

It doesn't matter all that much actually.
