Why the upper band of vhf frequency is considered as uhf frequency?
Different people see the boundar between VHF and UHF differently. I tend to regard UHF as starting at 200 Mhz.
What does vhf and uhf mean?
Very High Frequency and Ultra High Frequency. They are ranges of frequencies of radio waves in the electromagnetic spectrum. VHF ranges from about 30MHz to 300MHz, UHF is from about 300MHz to 3GHz. They are further subdivided into bands for; marine, amature, and other 2 way radio use, also designated channels for television and radio broadcast stations, as well as other uses throughout the world. In the US on the now defunkt analog television system VHF channels were 2-13 UHF channels were 14-83.
Why do uhf and vhf relate to television broadcasts?
Early television broadcasts were transmitted on VHF (very high frequency) radio channels. They moved to UHF (ultra high frequency) and have remained on that band since. These bands are used for terrestrial broadcasts. Satellite broadcasts use even higher frequencies.
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
Can HF radios communicate with VHF or UHF?
No. The acronyms stand for different, non-overlapping frequency ranges. Since the #1 immutable requirement for radios to be able to talk to each other is that they be on the same frequency, and since HF, UHF, and VHF radios are by definition on different frequencies, that match would be harder to operate successfully than a mixed marriage.
How do you receive vhf?
You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.
What are the wavebands in order of increasing frequency?
Microwaves UHF VHF MF HF LF

What are the frequency ranges included in the following frequency subdivisions?
What are the frequency ranges included in the following frequency subdivisions? MF, HF, VHF, UHF and SHF
Do the police use UHF or VHF radios?
it rely depends where you are. UHF stands for ultra high frequency and vhf stands for very high frequency. vhf has ben around longer than UHF making them cheaper to use but UHF means smaller antennas and better output. vhf is better in rural locations with expectations to be used in close proximity because buildings and natural barriers affect them. UHF can easily get through buildings and natural barriers but you pay lots more for them. but any to answer you question they do use both just ask your locals what they use.
What is the frequency range of the PRC-113?
VHF: 116-149.975 mhz UHF: 225-399.975 mhz
Abbreviation for VHF radio?
Very High Frequency.
