SAR-2309-28KF-E2 & SAR-2309-28KM-E2WR-28 Pyramidal Horn Antenna, 23 dBi Gain with 2.92 mm
Coax Input
SAR-2309-28KF-E2 & SAR-2309-28KM-E2 are Ka-band pyramidal hornantennas with end launch (180°) 2.92 mm coax connectors to cover thefrequency range of 26.5 GHz to 40 GHz. The antennas offer 23 dBi
nominal gain and a typical half power beamwidth of 10 degrees on the Eplane and 11 degrees on the H-plane. The antennas support linear
polarized waveforms. Right angle (90°) 2.92 mm coax connectorconfigurations are available under models SAR-2309-28KF-R2 and SAR2309-28KM-R2

NOTE:
••

Test data is provided it is collected from a sample lot. Actual data may vary slightly from unit to unit. All testing is 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 device damage.
• Proper torque, 8.0 ± 0.4 inch-pounds (0.90 ± 0.02 Nm) should be applied. Eravant torque wrench, model
SCH-08008-S1, is highly recommended.
