Chapter 1:Lights,Camera,ACTION!
It all starts with a studio making a movie.You want to watch it,don't you?So you have a antenna at the top of your house.That antenna collects the signals.But let's go back to the very beginning.When the movie is made,it is sent out as radio waves.And those radio waves are sent to an antenna(AGAIN!),that sends the radio waves out to satellites out in the atmosphere.
Chapter 2:Where next from the atmosphere?
There is a huge variety of antennas.Here is a list of some of some:
- Yagi-Uda antenna
- Helical antenna
- Spiral antenna
- Dipole antenna
- Short dipole antenna
- Horn antenna
AND A WHOLE LOT MORE!
Now,antennas,can be of two types:Omni-directional and Uni-directional(uni meaning one,unicycle,uniform). An Omni-directional one will pick up a signal from any angle,but a uni-directional one will pick up a signal from only one angle.Your TV is connected using wires,to a plug-in point.
Chapter 3:Your movie for you!
If you look up top of your roof,you will see cables coming from it.That is where your radio waves gets sent to!Well,your antenna,that gives the radio waves to the cables.the the radio waves gets sent to the plug-in point,and then they are sent to the wires,that is connected to your TV,and so you can see your movie!
