Ka Band Monopulse Cassegrain Antenna, 34 to 36 GHz,
43 dBiSAY-3433634310-28-U5-MP is a Monopulse Cassegrain antenna that
operates from 34 to 36 GHz, and has a half power beamwidth of 1.0
degrees. The antenna offers a nominal gain of 43 dBi in the Sum Port,and 36 dBi in the H-Port and V-Port. The antenna has three WR-28
waveguides with UG-599/U compatible flanges, which are designated as
Sum Port, V-Port, and H-Port. The antenna can support linear polarized
waveforms and is designed and manufactured for indoor applications.

NOTE:
••

•

On condition that test data is provided it is collected from a sample lot. Actual data may vary slightly from unit to unit. Alltesting is performed under +25 °C room temperature.
On condition that simulated test data is provided, actual measured data may slightly vary.
Eravant reserves the right to change the information presented without notice.

CAUTION:••••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradation and may damage ordestroy the unit.
Any foreign objects in the antenna will cause performance degradation and possible device damage.
For 1 mm connectors proper torque should be applied: 4.0 ± 0.15 inch-pounds (0.45 ± 0.02 Nm). Torque wrench model
SCH-06004-S1 is highly recommended.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
