Half octave single linear feed horns
The medium gain corrugated horn is the fi rst choice
for general purpose compact ranges. It offers the
best overall performance in regard to amplitude taper,
cross polarization performance, refl ector edge illumi-
nation, chamber wall illumination, and feed leakage
into the quiet zone.
The low gain corrugated feed horns offer lower
amplitude taper (typically 0.3 dB over the full quiet zone
versus 0.8 dB for the medium gain horns) at the
cost of slightly degraded other parameter. It is also
frequently used on compact range systems with
shorter focal length, which require an illumination cone
angle of ± 16 deg. Other advantages of the low gain
feeds are lower weight and the availability of a full
octave frequency bandwidth up to 8 GHz.
