SAR-1725-28KF-E2 & SAR-1725-28KM-E2

Rev 1.3

Description:
Model SAR-1725-28KF-E2 and SAR-1725-28KM-E2 are Ka-band
pyramidal horn antennas with end launch (180°) 2.92 mm coax
connectors to cover the frequency range of 26.5 GHz to 40 GHz.
The antennas offer 17 dBi nominal gain and a typical half
power beamwidth of 23 degrees on the E-plane and 24
degrees on the H-plane. The antennas support linear polarized
waveforms. Right angle (90°) 2.92 mm coax connector configurations are available under models SAR1725-28KF-R2 and SAR-1725-28KM-R2.

Note:• This antenna is a mature product. The reasons for only providing simulated data can be found in
the following blog here.
• All testing was performed under 25˚C case temperature.
• Eravant reserves the right to change the information presented without notice.
Caution:• Any foreign objects in the horn antenna will cause performance degradation and possible device
damage.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
