Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 through 216 MHz, and the UHF band, which comprises channels 14 through 51 and occupies frequencies between 470 and 700 MHz.
What frequency band does TV use?
For TV aerial reception and terrestrial TV services the Ultra high frequency (UHF) band is used. The UHF is the frequency band between 300Mhz-3Ghz, within this band we have the digital TV signals and the satellite Intermediate frequency band.
What are the two different frequency bands?
| Band Frequency Range Wavelength | VHF 30 MHz – 300 MHz 1,000cm to 100cm | UHF 300 MHz – 1 GHz 100cm to 30 cm | L band 1 to 2 GHz 30cm to 15cm | S band 2 GHz – 4 GHz 15cm to 7.5cm |

What is VHF and UHF?
VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency . This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
What are the different types of frequency bands?
| Frequency Band Name Acronym Frequency Range | Medium Frequency MF 300 to 3000 kHz | High Frequency HF 3 to 30 MHz | Very High Frequency VHF 30 to 300 MHz | Ultra High Frequency UHF 300 to 3000 MHz |

What radio frequency is harmful to humans?
Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Which WiFi frequency is best?
Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV.
How do I know what frequency my TV is on?
A: A TV channel, such as 2.1, 4.1, or 5.1, might be displayed on your TV, but that does not mean it is a VHF frequency. You can locate the actual broadcast frequency channel at www.tvfool.com . Select the TV Signal Locator and enter your home address.
Is digital TV signal VHF or UHF?
The majority of digital TV stations currently broadcast in the UHF band , both because VHF was already filled largely with analog TV when the digital facilities were built and because of severe issues with impulse noise on digital low-VHF channels.
What is the frequency for RTE 1 on TV?
RTE 1 and UTV Ireland are both on 770 MHz , channel 58. 738 MHz is channel 54 which carries RTE 2, TG4 and other channels. You shouldn’t be getting UTV Ireland on that frequency.
Are police radios UHF or VHF?
Police radios operate in a 700/800 MHz UHF band .
Who uses UHF frequency?
Who Uses UHF and VHF? UHF is typically used by public safety officials like fire, police, and EMS with tv channels of 77-80. UHF is used for common purposes like phones, televisions, and ham radio operators.
How do I know if I have VHF or UHF?
If you see both V-shaped elements and a smaller cluster of straight elements on the same antenna, it receives both signals. The simplest indoor antenna is the basic rabbit ears design, which receives VHF. A loop-shaped antenna, whether it’s arranged horizontally or vertically, is for UHF .
What is the difference between band and frequency?
A frequency band is a range of frequencies. They’re usually referred to by the wavelength (e.g. 40 meters is the band from 7000 KHz to 7300 KHz). A frequency is the reference point for tuning your transceiver.
What is very low frequency used for?
| Frequency range 3–30 kHz | Wavelength range 100-10 km |

What is the frequency of the human voice?
In general, the fundamental frequency of the complex speech tone – also known as the pitch or f0 – lies in the range of 100-120 Hz for men , but variations outside this range can occur. The f0 for women is found approximately one octave higher. For children, f0 is around 300 Hz.
