Broadcast TV in the US occupies selected frequency bands between 54 and 698 MHz. It used to go all the way up to 896 MHz, but the frequencies formerly used for channels 52-83 have been reassigned to other purposes.
Each individual TV channel occupies a band of about 6 MHz.
If you're happier expressing frequencies in meters (of wavelength), this corresponds to from about 5.5 meters to around 0.5 meters. There are some pretty big gaps in there, though; TV doesn't use every frequency in that range (among other things, FM radio takes a chunk of it).

Difference between uhf and vhf?
The frequency. Oddly enough, uhf actually stands for Ultra High Frequency and vfh stands for Very High Frequency. VHF for old TV covered the range 90Mhz to 150Mhz UHF for modern TV covers the range 400Mhz to 800Mhz
What is 3 -30 megahertz?
3 - 30 megahertz is a frequency range within the radio frequency spectrum, commonly used for radio broadcasting, television broadcasts, and various communication systems. It falls in the low frequency range compared to higher frequency bands like microwaves or infrared.
The frequency range 30MHz - 300MHz is?
The frequency range 30MHz - 300MHz is part of the VHF (Very High Frequency) spectrum. It is commonly used for applications such as FM radio broadcasting, air traffic control, and television broadcasting. It falls between the HF (High Frequency) and UHF (Ultra High Frequency) ranges.
What is the standard frequency spectrum range of VHF?
The standard frequency spectrum range of VHF (Very High Frequency) is commonly defined as 30 MHz to 300 MHz. This range is widely used for various applications such as FM radio broadcasting, television broadcasting, amateur radio, and air traffic control.
What is the frequency range of intermediate frequency?
NTSC TV IFs:video, 45.75MHzchroma, 3.58MHzaudio, 4.5MHz
What are two main bands of television wave frequencies?
Amplitude and frequency
What are the maximum and minimum frequency of radio waves?
Radio waves have a frequency range that typically spans from about 3 kHz (kilohertz) to 300 GHz (gigahertz). The minimum frequency of 3 kHz corresponds to the very low frequency (VLF) range, while the maximum frequency of 300 GHz falls within the extremely high frequency (EHF) range. This broad spectrum allows radio waves to be utilized for various communication technologies, including AM and FM radio, television, and wireless networks.
What type of electromagnetic wave is used for television?
Television signals primarily rely on electromagnetic waves within the radio frequency range, specifically UHF (Ultra High Frequency) and VHF (Very High Frequency) bands. These waves are used to transmit audio and video information to TV antennas for reception by television sets.
What is 88 to 108 MHz?
108 to 108 MHz is the radio frequency range assigned to the audio portion of broadcast television channels.
What is a lock in range and a capture range?
Lock range is the input frequency range of the PLL over which out frequency changes in step with input frequency, where as capture range is the frequency range over which oput starts to responds to input frequency change.

What is one example of a low frequency wave?
One example of a low frequency wave is a radio wave, which has a frequency range typically between 30 Hz and 300 GHz. These waves are used for broadcasting radio and television signals, as well as for wireless communication.
