Abstract
There exists a need for antennas that combine low profile nature and the ability to operate over a multioctave band without appreciable degradation in impedance bandwidth or radiation pattern. The authors present a new antenna configuration which has a height of 1.75 meter and employs either two or three monopole elements in conjunction with a multifeed switching circuit. The antenna system is designed to perform over the 30-450 MHz band.<>
