What is the frequency of TV signal?
We know that digital signals require higher bandwidth than analog signals. Space wave communication is used for transmission of frequencies more than 30 MHz. Thus, the frequency range used for TV transmission is 30MHz-300MHz.
What TV channel is 61.25 MHz?

| 3 | 60 | 61.25 |
| 4 | 66 | 67.25 |

What is the wavelength of a TV?
1 – 10 meter
TV waves have a wavelength range of 1 – 10 meter.
What happened to analog TV frequencies?
Full power analog TV broadcasts officially ended on June 12, 2009. There may be cases were low-power, analog TV broadcasts could still be available in some communities. These should have also been discontinued as of September 1, 2015, unless the FCC granted special permission to a specific station licensee.

First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
How do TV antennas receive signals?
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.
What are TV waves?
The antennae on your television set receive the signal, in the form of electromagnetic waves, that is broadcasted from the television station. It is displayed on your television screen. Cable companies have antennae or dishes which receive waves broadcasted from your local TV stations.

Do TV Antennas need line of sight?
A: For the best performance, we typically recommend placement of your TV antenna at the highest point available to you and with a clear line of sight to the broadcast towers to minimize the possibility of obstructions between your antenna and the broadcast towers it is receiving signals from.
How do TV signals travel?
The TV signal is carried by wire to an antenna, which is often on a high mountain or building. The signal is broadcast through the air as an electromagnetic wave. These waves can travel through the air at the speed of light but not over very long distances.
