MEASUREMENT PROBES

Which CR feed horn do you need?

Particularly suited for Main characteristics

Low Gain Compact range with Lower amplitude

short focal length taper, lower weight,

options for full

octave bandwidth,

higher reﬂ ector

edge and wall

illumination, higher

cross-polarization

Medium Gain General purpose Best overall

standard ORBIT/FR performance,

compact range compliant to the

compact range

catalogue speciﬁ cations

High Gain Individual applications Higher amplitude taper,

of antennas smaller lower reﬂ ector edge

than nominal quiet zone and wall illumination,

size with high sidelobe reduced quiet zone size

accuracy requirements

Mechanical drawing Medium gain feed horns with dual polarization for more efﬁcient range utilization are available upon request. Half octave single linear feed horns The medium gain corrugated horn is the first choice for general purpose compact ranges. It offers the best overall performance in regard to amplitude taper, cross polarization performance, reflector edge illumination, chamber wall illumination, and feed leakage into the quiet zone.
