NSI Compact Antenna Test Range Reflector - 20' x 20' (6.1 m x 6.1 m)

DESCRIPTION

NSI offers a line of Compact Antenna Test Range (CATR) reflectors for use in far-field antenna test systems. These reflectors use an optimized blended rolled-edge reflector termination resulting in minimum level of diffraction The ultra-lightweight graphite-epoxy-honeycomb composite design provides an extremely rigid and stable system with low Coefficient of Thermal Expansion (CTE) and very high flexure strength.
CAPABILITIES

The rolled edge reflector is a graphite-epoxy composite design using aerospace-grade materials It includes a precision 20’x20’ Tooling Steel frame structure support. The system includes broadband / wide beamwidth feeds covering 2-18 &18-40 GHz. The reflector surface tolerance can support measurement up to 110 GHz.
