The power of the signal would be high or low if you are transmitting in omnidirection antenna as compared to directional antenna?
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.
What is the wave source of a radio wave?
The source is the RF current in the transmitting antenna.
What is the difference between transmitting and receiving antenna?
There is no difference between the two.
Is the radio a source of the waves?
The source is the RF current in the transmitting antenna.
How far does a digital tv signal travel from a tower?
That truthfully depends on the transmitter's transmitting power, height of the transmitting antenna and the terrain.
Show that doubling the transmission frequency or doubling the distance between transmitting antenna and receiving antenna attenuates the power received by 6 dB?

Are you really transmitting voltage in amplitude modulation?
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.
What is the average distance for transmitting terrestrial microwave?
With enough power and antenna gain the answer would be line of sight.
What type of energy transfers information from a radio station to the radio?
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
What energy conversion takes place in a transmitting and receiving antenna?
sound energy is converted to electrical energy from the station through wind energy radio wave is sent and intercepted by an antenna to electrical and sound energy.
Why are car radio antenna's vertical?
It's called polarization and it relates to the orientation of the transmitting antenna. If the transmitting antenna is vertical, the majority of the transmitted energy is vertically polarized so it stands to reason that to pick up the most signal the receiving antenna should be the same way. In a moving auto though more is now understood about the propagation path the signal takes before it actually gets to the moving radio. The signal isn't line of sight but takes a lot of reflective paths before it actually gets to the antenna. The signals are reflected so many times that polarization is altered and can be any direction by the time it gets to the car receiver. Radio stations get around this anomaly by circularly polarizing the signal at the transmitting antenna. Many car antennas are now embedded in the glass windows instead of wire whips formally mounted to the fenders.
