The purpose of the antenna is to intercept radio waves from the desired television stations and convert them to tiny radio frequency alternating currents which are applied to the television's tuner, which extracts the television signal.

What does a TV antenna do?
To simplify it, a TV antenna is a collection of specially arranged wires or metal elements designed to pick up broadcast signals from TV networks. HDTV antennas receive television broadcasts via electromagnetic signals and translate them into video and audio to display whatever programming you want to watch.
How does a radio antenna work?
How a transmitter sends radio waves to a receiver. 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
Does TV still need antenna?
You will still require a HD Digital TV Antenna to pick up local, over-the-air broadcasts for free. ... Unless you provide your own tuner, you won't be able to enjoy over-the-air channels and will still require a Set Top Box.
What channels can I catch with an antenna?
Once you get an antenna, you can tune in to local broadcast channels, such as ABC, CBS, Fox, and NBC, as well as PBS and Telemundo. It's free TV.
Can you use a radio antenna for TV?
As you can see the whole FM band is between VHF channels 6-7. That's why an FM antenna can't do all the TV channels. One last thing, I am assuming that you have a newer TV that can receive digital TV signals. If you don't you will still need a converter box.
Do smart televisions need an aerial?
So, can you watch a smart TV without an aerial? If you want to watch a TV station, you WILL need a TV aerial to receive TV Channels. ... However, since you have a smart television it should have internet TV services such as Netflix, Amazon, BBC iPlayer and more built in. You don't require an aerial to watch these services.
Will a smart TV work with an antenna?
You can use a TV antenna with any kind of real television, including a Smart TV. ... That's the device that accepts an antenna signal and converts it to the picture and sound your television delivers to you (currently this is the ATSC 1.0 standard but will later change to 3.0).
Do some TVs have built in antennas?
While pretty much every TV available can receive existing antenna broadcasts, only a handful of new 2020 and 2021 TVs have built-in NextGen TV tuners. They're available now or coming soon from LG, Samsung and Sony.
How does an antenna receive signals?
The antenna at the transmitter generates the radio wave. A voltage at the desired frequency is applied to the antenna. ... At the receiver, the electromagnetic wave passing over the antenna induces a small voltage. Thus, the antenna becomes the signal source for the receiver input.
Do antennas need power?
An antenna itself is just a metal stick. It doesn't need power to function. ... When the antenna signal reaches the antenna, the antenna's molecules begin vibrating in a way that corresponds to the antenna signal. A weak electrical signal then flows through the antenna and into the cable.
What is the functioning role of an antenna in receiving mode?
An antenna receives electric signals from the transmitter circuits and converts them into electromagnetic waves. ... During the receive mode of operation, an antenna converts the electromagnetic waves into electric signals.
Are antennas worth it?
Should You Get a Digital TV Antenna? TV antennas let you pick up extra channels in your area. They're especially great if you want to (or already have) cut the cord. These live over-the-air channels may include ABC, CBS, FOX, NBC, PBS affiliates and independent stations.
