VHF uses the 6 Meter Band (50-54 Mhz), the most popular VHF band - 2 Meter Band (144-148 Mhz) and the 1 1/4 Meter Band (222-225).
UHF uses the most popular UHF band - 70cm Band (420-450 Mhz), the 902-928 Mhz area and the 1200-1300 Mhz area.

What is the frequency range of the PRC-113?
VHF: 116-149.975 mhz UHF: 225-399.975 mhz
Can HF radio communicate with UHF or VHF radios?
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.
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
What is the history of VHF radio?
history of vhf radio
Will a 27mhz cb antenna work on your uhf cb radio?
No, this is not a wise move to make. The antenna metals are not the same. you have to know that antenna metals are different within all Mhz. 2nd- The connectors are different. CB has a wider coax connector and Uhf us smaller. Radio Range/ distance will be less if you use a short wave antenna known as CB. Best to get a High wave antenna- UHF. 27 Mhz is cb radio and the waves are low and long (about 11 meters). 400-460 Mhz is UHF and the waves are high and short (about 67 centimeters). You would need a UHF radio antenna to get the best SWR. Installing a UHF antenna on a car it would require a proper uhf antenna and coax and drilling and using only a UHF Coax cable with the connector. Or buy the Uhf magnet antenna. They are hard to find in your local city and they are pricy because you cant buy them used or at cb shops. you will have to buy one online or go to a Junk yard and find a Police car that has one on top of car. You can Mod Coax cables only if its a UHF cable and antenna. Grounding a car UHF antenna in house can be difficult. Don't run ground to AC ground! you can damage radio. Run Ground wire to the dirt outside and dig a hole and fix with a little water and keep hot coax separated from ground on uhf. Best is to run this to Gutter on roof. Do not MOD CB coaxes with UHF antenna or mix with magnet antenna or CB, VHF, Marine radios. You will waste your time. 800 Mhz police antenna will be your closest match if you decide to do this. It goes by the wave and wave length. Keep Digging
Can a uhf antenna pick up vhf signals as well?
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.
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.
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
How can you connect an antenna to uhf and vhf to get both uhf and vhf on tv at the same time?
First, you need an antenna that is both uhf and vhf comaptible. Usuaully it will have a pair of rabbit ears (vhf) and a center loop or plate (uhf). Make sure the rabbit ears are completely extended then just re-scan your channels on your digital box or your hdtv.
Is een draadloze microfoonset met VHF storingsgevoeliger dan UHF microfoons?
Een draadloze microfoonset met VHF is storingsgevoeliger dan UHF microfoons.
What station is Required vhf?
VHF is the more common for tv channels, you are probably thinking UHF
Can vhf transmitter use uhf multicoupler?
I wouldn't think so. The uhf coupler is made NOT to pass vhf freqs. The transmitter and the coupler are made to operate in different bands.
Should you use UHF antenna with digital converter box or VHF?
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
Will the new digital signals be in both UHF and VHF?
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
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.
Is digital tv on both the uhf and vhf spectrum as was analog tv?
Yes
When should you use VHF over UHF?
A couple of points: When you're on the receiving end, UHF signals have a few disadvantages over VHF signals, owing to UHF's higher frequencies: 1) UHF transmitters tend to be less powerful than VHF transmitters 2) Transmission lines lose appreciably more signal at UHF than VHF, and that's just for transporting the signal from the transmitter room to the antenna 3) UHF signals tend to get weaker more quickly than VHF signals as they propagate outwards from their transmitters 4) UHF receivers tend to be less sensitive than VHF receivers UHF signals have one particular advantage over VHF signals: The smaller wavelengths of UHF signals allow for a smaller antenna to provide the same performance as a larger VHF antenna. Alternately, you can make the UHF antenna larger for enhanced performance, and it might still be small compared to a nominal VHF antenna. (Please pardon all the vague, qualitative references.) High-performance antennas for UHF that are not especially huge can more-than-compensate for lower power transmitters, lossier transmission lines, higher path-losses, and less sensitive receivers. Another advantage of UHF (and microwave) is that there tend to be more frequencies available than at the lower VHF frequencies. As technology advanced over the years, radio-spectrum habitation moved from the lower frequencies to the higher frequencies. Necessarily, the tendency is for lower, "older" (VHF) frequencies to be more crowded than higher, "newer" (UHF / microwave) frequencies. More than likely, the frequency you operate on will be determined by the radio-communications-licensing authority in your country (i.e., the FCC in the USA). A particular service might have allocations available in more than one band, i.e., VHF and UHF, and then it's up to the Engineering Department to decide which of those legally available frequencies to chose for their system.
