These are generally lower powered, handheld radios with a maximum power output of 0.5 watts, resulting in a shorter range.
Depending on the surronding terrain, the range can vary from between a few hundred meters in a built up area to a few kilometers in open ground
You can use licence-free radios for either business or personal use on any of eight UHF frequencies.
Licence-free two way radios (also commonly known as PMR446 radios for the frequencies they use) are manufactured with the frequencies already programmed in.
Power sources can vary, from basic models which use AA cells to more advanced models which use Li-ion rechargeable packs.
Benefits of a licence-free radio

  • Less expensive than licenced radios
  • Easy to use
  • Pre-programmed radio frequencies
  • No call charges
  • No contracts
  • Rechargeable versions give good operating time
  • New digital technology has improved voice quality and performance
  • No licence required!

Disadvantages of licence-free radios

  • Lower power, so their range is shorter (approximately 3km maximum)
  • Their popularity means the channels can often be congested
  • Not suitable for emergency use as channel usage is on a first-come-first served basis
  • If users are too far apart they may suffer interference from other two-way radios within range
