SAC-2309-28-S2

Rev 1.3

Description:
Model SAC-2309-28-S2 is a Ka-band conical horn antennathat operates from 38.5 to 43 GHz. The antenna offers 23 dBi
nominal gain and a typical half power beamwidth of 9
degrees on both E-plane and H-plane. The horn also offers
typical sidelobes of -15 dB on the E-plane and -18 dB on theH-plane. The conical horn can support linear polarization. The
input of this antenna is a WR-28 waveguide with UG-599/U-M
flange.
