This omni-directional antenna provides operation over an ultra wide bandwidth from an incredibly small antenna size. This antenna is of value to a variety of organisations involved in monitoring and managing the RF spectrum. It is a versatile substitute for multiple antennas currently deployed in the Electronic Warfare and Surveillance communities.
