that is obvious
Watch it Dave, that last statement is Gaussian and lacks the "t"
variable making it static. Getting the jump on Art and adding "t", it
becomes:
( my knowledge about antennas will always be zero at this rate)
This added time dimension cannot be in dispute, can it? It brings
equilibrium, was proven by Newton, and thoroughly demolishes
Einstein's work in the same stroke. (Patent Pending, so it must be
true).
Thanks for the free English lesson.
My knowledge increases a little after yours:
"Actually you have mixed up two different characteristics. Polarity
and polarization are NOT the same thing. With RF radiation, the wave
is constantly changing polarity (that is why the source of RF is
called alternating current), but within the "line of sight" of the
antenna, the polarization for a dipole is defined by its angle to the
earth as viewed by the observer.
If you see an horizontal dipole, it produces alternating polarities of
waves with horizontal polarization. If you see a vertical dipole, it
produces alternating polarities of waves with vertical polarization.
RF energy is ALWAYS changing polarity."
My knowledge will be full if you write something about the monopoles.
