A two-way radio is based on the electronic wave to send information. So, due to the different weather and environment, the distance range is different. And the transmitting power is the primary factor to affect the range. In general, the high power of FRS radios is 2W and 0.5W for PMR446 radios, 5W for GMRS radios and licensed radios, and some higher power on amateur radios and mobile radios.
