SAR-1725-28KF-R2 & SAR-1725-28KM-R2Rev 1.3

Description:
Models SAR-1725-28KF-R2 and SAR-1725-28KM-R2 are Kaband pyramidal horn antennas with right angle (90°) 2.92mm coax connectors to cover the frequency range of 26.5
GHz to 40 GHz. The antennas offer 17 dBi nominal gain anda typical half power beamwidth of 23 degrees on the Eplane and 24 degrees on the H-plane. The antennas support
linear polarized waveforms. End launch (180°) 2.92 mm coax connectors are available under models
SAR-1725-28KF-E2 and SAR-1725-28KM-E2.

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 room temperature.
• Eravant reserves the right to change the information presented without notice.
Caution:• Any foreign objects in the antenna will cause performance degradation and possible devicedamage.
• 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.
