The short answer is , metal antenna elements are tuned by length and diameter to resonate at a electro magnetic frequencies of the tv channels. The vibrating electrons vibrate each other , even over long distance. Some every day examples of this are , electric guitar , the electrons in a vibrating metal string vibrate the electrons in the electro magnet under the metal string, and this vibrating electron energy is connected to a amplifier.
A simpler example is a 'toaster' , the vibrating 'electrons/electric' flowing through the wires in the toaster make the electrons in the wires vibrate very fast and with a lot of energy and this is high rate of friction between the electrons makes heat. Friction makes Heat and light , light is vibrating electrons vibrating at a rate/frequency that you can see with your eyes The same thing in a light bulb.
The resistance of tungsten wire to the to the vibrating electrons causes more friction and this makes heat and light.
Electricity , is in fact vibrating electrons.
The different rates of vibration convey different information. Type of information are in fact , heat or light. Radio or Television or Etc,.

∙ 12y agoAn antenna is built and tuned specifically to resonate at a certain frequency or set of frequencies. In receiving, this resonance will appear as an RF voltage across the antenna, or between the antenna and ground. This RF voltage is usually modulated in order to carry information, for example a radio station. You generally use a receiver of some kind to "decode" this information, and make it usable to humans again, for example, play the music as audio through a loudspeaker.

Why does a tv with built in ntsc-atsc tuner do not pick up antenna signals?
On the settings or set up menu the tuner might not be set to receive off air signals or might be in the cable mode or it might be in the analog mode and you no longer have any analog stations to receive. Check to see if you are in the digital and antenna modes.
Can a uhf antenna pick up vhf signals as well?
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.
Does a digital TV have a built in antenna or tuner that will pick up over the air signals without an outdoor antenna?
I have not seen any digital TVs with a built in antenna. Depending on where you live you could use a simple "rabbit ears" setup or even one with a built in amplifier if you're a bit far from the stations.
What basic law of electromagnetism explain how an antenna picks up a radio signal?
RF energy is transmitted through an electromagnetic field. Once the field meets the receiving antenna, voltages are produced by using the antenna as a conductor. RF voltages induced by the antenna are passed on to the receiver then reconverted to transmitted RF information.
What is the purpose of the antenna on a radio and TV set?
Pick up the electromagnetic radiation (in the radio or TV bands) so that it can be brought into the set as electrical signals. This is analogous to the purpose of your eyes: pick up the electromagnetic radiation (visible light) so that the information can be brought into your brain as nerve impulses. However the antenna is usually just passive, whereas you eyes contain much of the active processing "circuits" that extract information that would be inside the radio or TV set.
How do you write antenna in plural form?
The plural of antenna is:antennae, if you're referring to the appendages of an insect;antennas, if you're referring to aerials for picking up radio/tv signals.
Is there any LCD TV which is received signals directly from satellite without antenna?
No. Satellite signals are very weak- after all, they are small devices, trying to spray a signal all over a continent. To pick them up requires an antenna pointed directly at them (no fun watching five satellites at the same time!) and a bulky bit of technology called a "low noise amplifier". Neither could be built into an LCD TV. Sorry.
How do you spell intena?
The word is spelled antenna. A good example sentence using this word is, "Most cars have an antenna on them to pick up radio signals."
Will a tv that has a digital tuner pick up over the air digital broadcasts?
It sure will! (But you still need an antenna)
How do wireless antennas share information?
they dont. An antenna is simply a piece of metal hooked to a device (normally a radio or a walkie-talkie). A receiver (for example, a radio) pick up electrical signals from the antenna, and a transmitter sends them to the antenna. They can be combined to form a transceiver which then sends and receives signals from the antenna.
What antenna to use to pick up local tv stations in McKinney TX 75069?
You need a special digital version of the old-fashioned "rabbit ears" to pick up digital TV broadcasts over the air.
Will a digital tv still receive and process an analog signal from an outdoor antenna?
No. There will be no analog signal to receive and process from the outdoor antenna. The only signal coming from the outdoor antenna will be digital. When the conversion is complete. You will need to hook up your antenna directly to the TV. Your conversion box will be worthless as far as analog to digital is concerned.
