Reflector
The reflector is a 75 cm reflector, consisting of a center hub and 4 interchangeable petals.
The petals are made entirely of carbon-fiber composite with the exception of the metallic
latches. The aluminum latches are used to secure the petals to the hub. Two smaller latches
along the edge of the petals attach the reflector petals to each other. The reflector weighs 3
kg (8.5 lbs). The reflector has been designed to meet wind load and thermal distortion
requirements; see
on page A-1 for more detail.

Base Unit and support legs
The Base Unit contains many subcomponents including the antenna control unit, GX
modem, GNSS (Global Navigation Satellite System) module, DC power supply, sensors and
WLAN module, in addition to environment-sensing technology that self-regulates system
temperature and atmospheric pressure equalization. Four local IP ports are available, Port 1
(Service port) or Port 4 (Management) is used for system control via the web interface.
The Base Unit has an embedded keypad and display to provide access to configuration,
control, and system monitoring tools.The antenna positioner is hard-mounted to the Base
Unit, and is class IP65 protected against dust and water ingress.
