Practical for security guards or for a group that are heading out on an adventure, these long range walkie talkies are the ideal choice. Using ultra high frequency (UHF) to communicate, this walkie talkie set comes with two controls so two separate parties can communicate with each other. The main advantage of UHF transmission is the short wavelength that is produced by the high frequency also the size of transmission and reception antennas is related to the size of the radio wave. Antennas are included in the package and using the frequency wave of 400 to 469.995MHz, you will have a good and clear signal if weather and distant permits.
