Antenna Components
The SR1500 antenna is a self-pointing mechanically steered Ku-band phase array
antenna. The Uni Pol version provides reception (Rx) by a single antenna array panel
at dual circular or linear polarizations. The Dual Pol version provides simultaneous
V/H or RHCP/LHCP on 1.5GHz band on three simultaneous connections. In addition,
the antenna can automatically search for, locate, and track a requested
communication satellite.
The antenna includes the following key components:
Rotating platform containing:
o Phased array panel
o Receive and polarization control units
o Elevation and azimuth mechanisms for panel movement
o GPS, motion sensors, and main CPU unit with a built-in RSSI tuner
Dual-channel rotary joint
Radio frequency transparent weather proof radome
Connector interface box
Static platform holding all antenna components
The major components of the antenna are shown in the figure below:
