With the evolution of modern High Frequency (HF) radio equipment and the increasing use of digital communication techniques, there is a requirement for an efficient, broadband antenna, which is capable of instantaneous operation over a very wide frequency range. <span style="margin:0px;padding:0px;border:0px currentColor;line-height:inherit;font-family:inherit;font-size:13px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;background-color:transparent">This may be desirable in order to maximise the availability of a communication path between locations, or it could be to improve the security of a communication, by using techniques such as frequency hopping or spread spectrum.</span></p>
