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.
A reflector antenna consists of one or more reflecting surfaces with a central horn feed and reflects incident electromagnetic waves. They are widely used in receive and transmit applications including ELINT, EW, direction finding, threat emitters, meteorological sensors and communication systems.
Our parabolic reflector antennas provide high gain and low sidelobes with low VSWR levels. COTS and custom designed linear, circular polarised and dual polar feeds are available with SMA, N, K type and waveguide flanges. Additional offset and prime focus parabolic reflector combinations can be supplied.
Our antenna specialists can also design bespoke antennas for specific requirements including shaped reflectors, quick assembly antennas, interchangeable feeds and light weight reflectors.
Steatite provides bespoke designs for direction finding spinning antennas, reflectors with a motorised pedestal and tracking capabilities. The Company also provides selective band Splashplate antennas with narrowband linear and dual polarised docking feed covering 2 to 22 GHz.
As with other Steatite products, bespoke designs or modifications may be accommodated.
