Which is stronger VHF or UHF?
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.
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.
Do police use 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.
Do UHF channels still exist?

How far can a Baofeng reach?
Your Baofeng UV-5R is a transceiver: that is, both a transmitter and a receiver. With a full battery and in full power mode, it will give you a range of about 10–20 km depending on obstacles.
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.
What two-way radio has the longest range?
