Microwave EM radiation travels only in a straight line - line-of-sight/point to point. Bouncing waves off of the ionosphere would accomplish this.

What is the quality of a signal?
The quality of a signal is a measure of how much the signal has changed during transmission. A high quality signal has changed very little. A low quality signal has other information in it which was not there in the original signal. The additional unwanted information is called noise.
What is pitch period?
The pitch period of a signal is the fundamental period of the signal, or in other words, the time interval on which the signal repeats itself. The pitch frequency is the inverse of the pitch period, which is the fundamental frequency of the signal.
What energy source does a microwave use?
They are powered by electricity of course, but the generate microwaves (an electromagnetic wave, like light - but of a higher frequency). We are surrounded by microwaves from the sun, satalites, and radiation from electrical dewvices, but microwaves concentrate the energy - heat happens where "beams" cross and excite the molecules of what they are passing through (i.e. heat).
How would you use the word 'signal' in a sentence?
One if by land and two if by sea is the signal you shall set for me! The signal's yellow light was more green than red, officer! Semaphore utilizes signal flags.
Can you use signal word in a sentence?
The crossing guard sent a signal to the children.
When microwave signal follows the curvature of earth it is known as?
ducting
What is the difference between radio horizon and optical horizon?
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
Is a microwave analog or digital signal?
Pasta signal.
Television signal cannot be received beyond a particular distance because?
curvature of earth
What is the word data means?
Data is a signal that model a phenomenon.
How are electrical signals turned into data in microwave transmission?
This is usually done by modulating a much lower frequency carrier with the signal, then superheterodyning this carrier upconverting it into the desired microwave band. A corresponding superheterodyne receiver downconverts the microwave signal to a lower intermediate frequency which is then demodulated to recover the original signal.
Fading effect in microwave system?
Fluctuatuions in received signal..
What is diffraction of a signal and what causes it?
Diffraction is the bending of signal at the sharp edges of the obstacles. Because of the wave nature of the signal the phenomenon of diffraction becomes possible
What is detector mount in waveguide and its function?
used to detect the microwave signal
What are five examples of electromagnet?

What are traffic controls?
