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..
Can UHF and VHF radios communicate?
It is not possible to match UHF and VHF frequencies, because UHF radios only communicate in UHF 430-470 MHZ range and VHF radios communicate in VHF 150-174 MHZ range.
What bands do cops use?
What types of police radar are used? Police radar guns operate on three frequency bands: X-band, K-band, and Ka-band. Most newer guns the police use operate on the super-wide Ka-band.
Who uses UHF?
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.

Does UHF and VHF still work?
Today digital television is broadcast in the UHF band, but VHF is still used for FM radio and marine-band radio, and amateur radio enthusiasts still broadcast on both bands. Because of the different characteristics of the two frequency bands, the optimal designs for UHF and VHF antennas are significantly different.
Do police use encrypted radio?
Police radio is a communications radio system used by law enforcement agencies all over the world. Many such systems are encrypted to prevent eavesdroppers from listening in.
What happened to UHF?
UHF generally had less clear signals, and for some markets, became the home of smaller broadcasters who were not willing to bid on the more coveted VHF allocations. 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.
Will a UHF antenna pick up VHF?
In fact almost all TV antennas can bring in VHF signals no matter what they’re designed for. For that matter, most of them can bring in cellular, police band, aircraft, what have you. They just don’t do it very well. An antenna has to be specially designed to reject other signals.
Which is better UHF or VHF wireless microphone?
UHF systems do not hold any large technical advantage over similar VHF systems. However, interference due to electrical equipment, digital devices and other electronic equipment is generally lower at UHF frequencies. … VHF systems have good sound quality and have a better battery life.
What frequency do cops use?
Police operate a P25 trunked digital radio system in the ESB (VHF 138-144 MHz) and ESC (UHF 494-502 MHz) bands.
Do I need a UHF radio?
UHF radios are great to communicate over shorter ranges from your vehicle. Known as the Ultra High Frequency radios, these can be used to send messages over a distance of 30 Km. … However, if you are not going to ultra remote places or destinations then the regular UHF radio is better than investing in an HF one.
Which radio frequency is best?
How to Select the Right Two Way Radio FrequencyVHF (Very High Frequency) at 136-174 MHz. Best Suited For: Outdoor applications where maximum range is required with little to no obstructions and typically used for rural two way radio systems. … UHF (Ultra High Frequency) at 403-470 MHz. … 900 MHz Onsite.
What is the difference between UHF and VHF frequencies?
UHF radio waves are much shorter in length than VHF, measuring around 12 to 24 inches. As a result antenna length is reduced as well as radio range. Anything from a building to a human body can interfere with UHF transmissions. … Low-band UHF overlaps with high-band UHF, low is 450-536 MHz and high is 470-806 MHz.
Can VHF talk to CB?
1 Answer. CB or its close relatives fall into the HF frequency range (covering somewhere around 26 to 28 MHz, depending on country), so anything that accurately calls itself a VHF radio will not transmit (and most likely will not receive) CB.
