Steatite parabolic reflector antennas provide high gain and low sidelobes with low VSWR levels, for receive and transmit applications including ELINT, EW, direction finding, threat emitters, meteorological sensors and communication systems.
COTS and custom designed linear, circular polarised and dual polar feeds are available either with SMA, N, K type and waveguide flanges. Additional offset and prime focus parabolic reflector combinations can be supplied.
The Company also provides selective band Splashplate antennas with narrowband linear and dual polarised docking feed covering 2 to 22 GHz. Millimeterwave Cassegrain antennas are also provided by Steatite’s partner Sage Millimeter.
As with other Steatite products, bespoke designs or modifications may be accommodated.
