Difference Between UHF and VHF

This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete.

What's the difference between UHF and VHF signals?

UHF and VHF radio frequencies operate at different wavelengths. A VHF signal sends relatively large radio waves, while UHF signals are sent on smaller waves that arrive closer together. When we speak of a UHF signal as having a "higher frequency," that's literally what it means.

Does VHF or UHF have longer range?

For most applications, lower radio frequencies are better for longer range. A broadcasting TV station illustrates this. A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles. A UHF station with a 60-mile coverage radius requires transmitting at 3,000,000 watts.

What channels are VHF and UHF?

In the US and Canada, the VHF television band occupies frequencies between 54 and 216 MHz and the UHF band between 470 and 890 MHz. In general, VHF channels are numbered 2 to 13 and UHF channels 14 to 51.

Are police radios UHF or VHF?

Police broadcast on frequencies in the UHF band. You are legally allowed to listen to unencrypted transmissions in these bands, but you need a license to broadcast.

Who uses UHF frequency?

They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.

Can VHF talk to UHF?

VHF and UHF Walkie Talkies can't talk to each other. ... VHF spectrum is mainly used in rural areas…a good example is the Australian mining industry. VHF equipment operates between the frequencies of 30 MHz and 300 MHz. FM radio and television broadcasts operate in this range.

Is UK TV a VHF or UHF?

digital TV standard adopted in the UK and the rest of Europe is DVB-T (Digital Video Broadcasting Terrestrial) which uses 8 MHz wide frequency bands for its transmission. ... From this chart it can be seen that the total UK interleaved spectrum, which is entirely in the UHF frequency range, is 256 MHz.

Do UHF channels still exist?

These issues are greatly reduced with digital television, and today most over-the-air broadcasts take place on UHF, while VHF channels are being retired. ...

UHF walkie talkies are ideal for businesses that operate in cities, across campuses, and where workers are going in and out of doors all day. VHF walkie talkies, on the other hand, are better in wide open spaces.

How far can a two-way radio reach?

Wattage and Range of Coverage: Many two-way radios claim they have a range up to 25 miles in optimal conditions. Real-world conditions are usually not optimal, and in most situations, a radio's actual range will be about 2 miles or less.
