SAC-1533-328-S2

Rev 1.3

Description:
Model SAC-1533-328-S2 is a K-band conical horn antenna that
operates from 24 to 33 GHz. The antenna offers 15 dBi nominal
gain and a typical half power beamwidth of 30 degrees on theE-plane and 36 degrees on the H-plane. The horn also offers
typical sidelobes of -16 dB on the E-plane and -28 dB on the Hplane. The conical horn can support linear and circularpolarization. The input of this antenna is a 0.328” diametercircular waveguide with UG-595/U-M flange.
