The power of the signal, as perceived by the receiver, will be lower with an omnidirectional antenna. This is because the omnidirectional antenna is transmitting in all directions, while the directional antenna is transmitting in only one direction.Think of the directional antenna as a lens, focusing proportionally more power in a smaller space.
The source is the RF current in the transmitting antenna.
There is no difference between the two.
The source is the RF current in the transmitting antenna.
That truthfully depends on the transmitter's transmitting power, height of the transmitting antenna and the terrain.

A Hertz antenna refers to a type of dipole antenna that was invented by the German physicist Heinrich Hertz. It is a simple antenna design with two conductive elements used for transmitting or receiving electromagnetic waves at radio frequencies.
what is ment by rhetorical norms
A transmitting antenna generates electromagnetic fields, including electric and magnetic fields, that propagate outward from the antenna. These fields interact with the surrounding environment and propagate through space to carry the transmitted signals. This relationship between the antenna and the fields it generates allows for the transmission of information wirelessly over a distance.
In a transmitting antenna, electrical energy from the transmitter is converted into electromagnetic radiation (radio waves) for transmission. In a receiving antenna, electromagnetic radiation from incoming signals is converted back into electrical energy for the receiver to process.
Assuming you have the output of an AM modulated voltage hooked up to a properly matched antenna, you're really transmitting electromagnetic waves. An electromagnetic wave, when intercepted by another antenna that is somewhat matched to the frequencies being used, induces a (tiny) voltage on that antenna that can be rectified, amplified, and turned back into sound waves on the receiving end.
With enough power and antenna gain the answer would be line of sight.
