*For a complete listing of all band letters and codes in use, refer to
Band Designation Table on page 176.
Patterns for all models in this series conform to the following
description: Beam width in E and H plane varies from 23° at the
highest frequency to 34° at the lowest frequency. Side lobes in
the H plane are all more than 20 dB down. First side lobes in the
E plane are 13 dB down, second side lobes are 18 dB down and
all other E plane lobes are more than 20 dB down.
Gain at Mid Frequency; 16.5 dB (with reference to isotropic radiation)
variation is 1.5 dB over total band about the mid band value.
See Waveguide Flange Data on page 188.
