SAO-2734030345-28-S1-WR

Rev 1.0

Description:
Model SAO-2734030345-28-S1-WR is a full band, Ka band
omnidirectional antenna that covers the frequency range of 26.5
and 40 GHz. This vertically polarized antenna offers 360 degrees
azimuth coverage with a 3 dBi typical gain and ±1 dB nominal gain
flatness. The antenna features a half power beamwidth of 45
degrees in its vertical direction. The RF port of the antenna isequipped with WR-28 waveguide with UG-599/U flange. Thewaveguide has an o-ring surrounding it to prevent small amounts
water from entering the antenna. The version with 2.92 mm (F) interface is offered under model
number, SAO-2734030345-KF-S1.
