Steatite manufactures COTS and custom designed vertical and slant polarised omnidirectional antennas suitable for EW, SIGINT, direction finding and spectrum management applications up to 40 GHz.
An omnidirectional antenna radiates or intercepts RF signals equally in all directions perpendicular to an axis. They are commonly found in devices such as mobile phones and routers.
Our COTS and custom designed vertical and slant polarised omnidirectional antennas are suitable for EW, SIGINT, direction finding and spectrum management applications from 0.01 GHz up to 40 GHz. 360° azimuth coverage.
We offer omnidirectional antennas with coaxial and rectangular waveguide interfaces. Our range also includes wideband and ultra-wideband antennas and all our standard and bespoke antennas can be provided with connectors and lensed radomes.
