The radio band that is right for you will depend primarily on your area of operation. If you will be operating the radios in largely open areas then you should operate on the VHF band. However, If you will be using the radios in or around large concrete structures or buildings you should operate on the UHF band. Simply put, if your area of operations is a low density suburb or a rural area then you should pick VHF. Inversely if you are primarily operating in dense suburbs or Cities then you should pick UHF. This is because VHF waves tend to travel farther in open areas whereas UHF waves tend to do better at penetrating obstacles.
