Hey, this is Berry Cola from the UK. I am a scientist. Recently, I have researched radio communication. One of the most difficult issues to make when choosing the correct radio is the bandwidth. VHF (Very High Frequency) and UHF (Ultra High Frequency) are the two main wavelengths used in vehicle-to-vehicle and vehicle-to-base communications. The range of the Motorola VHF Portable Radio is 30 MHz to 300 MHz, while the UHF range is 300 MHz to 3000 MHz. Both UHF and VHF radios are designed for a variety of purposes.
