Why the sky waves are not used in the transmission of T.V. signal?

when the frequency range is more than 40mhz then the ionosphere is totaly unable to reflect the signal back to the earth.as we know that the frequency range of TV signals is 100mhz-200mhz.so the transmission of TV signals via sky waves is not possible.

What is skywave propagation?
the propagation in which transmission and receiving of signals takesplace through the sky waves which having the lower frequency
What happens to light waves when they hit the water?
They bounce off it to the sky, hence the blue sky.
Which light waves disperse most in the atmosphere?
The violet and blue parts of the solar spectrum are dispersed most, and this leads to the characteristic "blue sky" as seen from Earth's surface in the daytime.
What is the color o0f the sky and y is it that the color?
Easy answer blue. which is wrong... Correct answer; we don't know. we will never be able to tell the correct colour of the sky. We just see it as blue as that is the way the light bounces off it and they way our eyes see it. The light is made up of 7 colours. The short light waves, red orange yellow green, just pass through our sight. as do the long waves, indigo and violet. However blue is just the right frequency for us to see. However it depends on the time of day. but the same rule applies, only certain types of waves are right. At least that is what would make sense. To be honest, the real question is what is the sky? I am sorry if i have bored you! But i hope this does help, and make you think! It has sure made me think!
Why are sky's blue why not violet?
The white light of the Sun consists of many wavelengths. When seen separately, each wavelength corresponds with a different color. The air molecules and particles of matter that make up our atmosphere scatter some of the Sun's light as it travels to Earth, especially the shorter wavelengths that give us the color blue. Coming to us from all angles in the sky, these light waves make the sky appear blue.
Suggest a possible communication channel for transmission of a message signal of bandwidth of 5 MHz?

What is the frequency in broadcasting?
Depending primarily on its frequency,radio wave may travel from the tranmitting to the receiving aerial in a number of ways.The most important of these are : 1. Ground waves (or Surface waves):they are useful for low frequencies of below 1000 KHz . 2. Sky waves: the transmission of radio waves in the frequency range of 3 to 30 MHz. 3.Direct waves( or line-of sight waves):At frequency above 30 MHz ,radio transmission cannot be carried out by ground wave or sky wave.
What are sky viewing cards used for?
Sky viewing cards are used to view Sky TV. The cards are placed into your Digibox which is connected to your television. The cards work as a sort of identification so that a signal can be sent to your Digibox.
What was the song used for the Samsung Instinct commercial?
The song that was used for the Samsung Instinct Commercial was "Signal in the Sky" (Lets Go!) by "The Apples In Stereo".
Sky wave antenna?
The term skywave is used to refer to the reflect radio waves from the ionosphere. ?æSkywave is used most frequently in shortwave radio broadcasts.
What happens to light waves when they hit the water?
They bounce off it to the sky, hence the blue sky.
How reliable is sky news?
Well, I believe the sky news has around a 95% of being right because they have a forecasting machine that sends a signal to the sky and then that signal feels around to determine what the weather it'll be. Then the signal calls back to the machine and the machine gives the about unpredictable forecast to the workers-somehow.
Are there flames in the Bermuda triangle sky?
no theres ocean waves
How you take signal from sky?
Using an Antenna and Receive RF Chain
Why can't i get a good tv signal?
cause the sky is falling down
Will a satellite dish receive a signal if its installed in the attic?
No, it will definitely not. It has to be outside, and facing the sky. If it is covered up in the attick, it cannot get signal.
