Antenna - Huawei OptiX RTN 600 ODU Manual

OptiX RTN 600 ODU
Hardware Description
About This Chapter
The microwave equipment uses the parabolic antennas to radiate and receive the electromagnetic
waves. The antennas that are described in this document are the parabolic antennas adaptive to
the OptiX RTN 600 SP/SPA/HP/LP/LPA ODU.
4.1 Equipment Type
The antennas are classified into two types, namely, the single-polarized antenna and dual-
polarized antenna.
4.2 Functions and Features
The antenna is used to convert between the RF signals transmitted from the ODU and the
electromagnetic waves radiated in the air.
4.3 Working Principle
An antenna comprises the reflector, feed boom, radome, shield, and mounting brackets.
4.4 Interface
The feed boom interface of the direct-mount single-polarized antenna is a waveguide interface.
The feed boom interfaces of the separate-mount single-polarized antenna and the dual-polarized
antenna are flange interfaces.
4.5 Antenna Diameter
Antennas that are of different types or operate on different frequency bands support various
diameters.
4.6 Specifications
The technical specifications for the antenna include electrical indexes and mechanical indexes.
The electrical indexes of the antenna include the antenna gain, half-power beamwidth, standing
wave ratio, and front-to-back ratio. The mechanical indexes of the antenna include the size,
weight, wind-protective feature, and ice/snow-protective feature.
