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.

Are UHF and VHF radios compatible?
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 is UHF radio used for?
Simply put, UHF CB or citizen band radio is a two-way radio system that uses the 476.4250–477.4125MHz, radio spectrum for short-distance communications.
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.
Are marine radios UHF or VHF?
They have limited battery power and no emergency channel. They operate in the 460 mHz UHF band between VHF radios and cell phones and transmit at 0.5 watts.
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.
What has better range UHF or VHF?
UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. UHF signals don't travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.
How far can UHF radios transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)
| Average Range Guidelines * | ||
|---|---|---|
| Wattage | Flat Open Terrain (miles) | Urban Areas (miles) |
| 4 watts (UHF) | 4 - 6 | 1½ - 3 |
| 5 watts (VHF) | 4½ - 6 | 1½ - 2 |
| 12 watt CB SSB (HF) | 8 - 15 | 3 - 5 |
Does UHF go through walls?
UHF radio waves generally only go as far as line of sight. Anything in the way of your sight will also interfere with frequency range, such as buildings, tall trees or any other obstruction. The transmission is high enough to penetrate through building walls, making indoor reception a possibility.
What is the best frequency for two way radios?
Ultra-High Frequency (UHF) operates at 400-512 MHz. UHF two-way radios are best if there will be any indoor use, because the shorter radio waves can more easily penetrate obstructions that are found inside buildings.
Why are Baofeng radios so cheap?
One of the reasons the Baofeng UV-5R radios may be so inexpensive is they are not aimed at a specific Niche, therefore they save money on big advertisements and promotions like the ham radio equipment manufacturers like Yaesu Icom and kenwood. They also do not test and advance any technology.
Do police use UHF?
The Baofeng and similar radios will program any public safety frequency in the VHF (150-174 MHz) and UHF (450-475MHz) bands. ... But, the vast majority of US police agencies still operate on radio channels compatible with the little $30 technological wonders.
Can police tell if you are listening to scanner?
The short answer is no. The long answer is no, with a long-winded explanation of how receivers can be detected but still with no practical police application. chaz0426 said: Sometimes right when I start scanning, it seems like a lot of the police and other utilities ect.
