SAY-3433632750-28-U5-MP

Ka Band Monopulse Cassegrain Antenna, 34 to 36 GHz,
27 dBiSAY-3433632750-28-U5-MP is a Monopulse Cassegrain antenna that
operates from 34 to 36 GHz, and has a half power beamwidth of 5.0
degrees. The antenna offers a nominal gain of 27 dBi in the Sum Port,and 21 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.
The higher gain version is offered under the model SAY-3433634310-28U5-MP.

NOTE:
••

All data presented 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.
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.
