High frequency carrier waves are needed for effective transmission of information signals because they:
*help in maintaining a practical size for the transmitting antenna and avoid it being very long.
*increase the power that is radiated by the antenna to enhance the transmission range.
*have the capability of converting wide band signals to low band signals.
*transmit many audio signals at a time from the same antenna without mixing them up.
