For every frequency there is an antenna that is perfect for radiating at that frequency. Unfortunately, it would be unrealistic to carry a separate antenna for every frequency that a communications center is capable of radiating. To overcome this problem, we use ANTENNA TUNING to lengthen and shorten antennas ELECTRICALLY to better match the frequency on which we want to transmit. Simply put, the antenna does not physically change length; instead, it is adapted electrically to the output frequency of the transmitter and "appears" to change its physical length. Antenna tuning is done by using antenna couplers.
