So I can feed my Ground plane or quad with a balun, then its a dipole?

no, it's not. be careful, you're making my case.

No, you said:

in order to be a dipole, it has to be fed with two signals, 180
degrees out of phase, and equal ampliude.

Be careful, your hurting your case, so by what you posted any antenna
can be a dipole if it meets the requirement of being fed two 180 out
of phase signals of equal amplitude?


a proper dipole is resonant, given a balanced feed, and therefore does not
put significant signal onto the coax shield. /or it's fed with ladder line,
from a balun in your tuner/



So, we all use improper dipoles, big deal. They are still dipoles,
spend some time building and using them, in real on the air tests, not
in your lab. Balun manufacturers won't make claims of significant
signal gains.

I'll keep building my dipoles without a balun, fed with coax, and be
very happy with how well they work.

no, there are several conditions, balanced feed is only one of them.

a balun isn't a gain device. neither is wire, but combine them, and you get
a gain device, which is a system called an antenna.

ok

Really? How much gain? If I have a dipole fed without a balun, how
much gain will I get when I add a balun to it?

Does it have to be a gain device to be able to call it an antenna
system?

You have already been given the definition of a dipole by several
people. If you prefer to call it something else, call it what ever
you want . It shouldn't take you more than a couple of weeks to
change all the text books and technical references to your definition
of a dipole.

If I have any questions on the correct way to build a dipole, I'll ask
Frank or Doc. They understand how to build them.
