UHF Two Way Radios are the most common two way radios found in use today. Most businesses using walke talkies today are using UHF. UHF two way radios come in 1, 2, 4, & 5 Watt Models and with as few as 1 channel and as many as 256. There are analog and digtial UHF two way radios with some being capable of doing both. UHF two way radios are typically compatible between Manufacturers. UHF two way radios require an FCC License.
