SAC-2507-470-S2

Rev. 1.3

Description:
Model SAC-2507-470-S2 is a K-band conicalhorn antenna that operates from 17.5 to 20.5
GHz. The antenna offers 25 dBi nominal gain
and a typical half power beamwidth of 8.5
degrees on the E-plane and 10 degrees on theH-plane. The horn also offers typical sidelobesof -18 dB on the E-plane and -28 dB on the Hplane. The conical horn can support linear and circular polarization. The input of this antenna is a 0.470”
diameter circular waveguide with UG-595/U flange.
