What is better UHF or VHF?
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 ham radios UHF or VHF?
Ultra High Frequency (UHF) For ham radio operators, you’ll use the frequency range from 420 – 450MHz. Unlike the reliability of VHF radio waves, UHF has a much shorter wavelength and is prone to interference from basically any solid object, whether that’s a building blocking your signal or even your body.
What bands are VHF and UHF?
In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.”
Is UHF or VHF better for outdoors?
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.
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.
Which has longer range VHF or UHF?
The main difference between UHF and VHF is range. UHF two-way radios have a range that is wider than VHF. This means that UHF frequencies have smaller waves that produce a greater range. They are more likely to pass barriers like rocks and trees easier.
Who uses UHF frequency?
Can you hear police on ham radio?
Yes and no — many ham radios are “wide band receive” capable, meaning they can receive outside of the ham bands. These extra receive frequencies sometimes include police frequencies. In some states, it is illegal to listen on those frequencies, but an exception is made for amateur radio operators and some others.
