8.1 - Theory Of Operation

Theory of operation describes the logic and functionality of the Winegard 2-Way
Satellite Internet System and is pertinent to all antenna and controller models.
8.1.1 - Antenna Drive Mechanism
The Winegard 2-Way Satellite Internet Antenna Systems have been modularly designed.
These systems can be accommodated with several different antenna sizes as well as
operate in conjunction with different satellite modem makes and models.
8.1.2 - Modem and Power
The antenna system requires an internet modem and suitable 110/220 volt AC power
source to operate when using Winegard's controller. The modem is required to power
the LNB.
8.1.3 - Cabling and Communication
The modem is connected to the Controller (IDU) through an ethernet cable and to the
antenna system through 2 RG6 (or equivalent) coaxial cables.
The RG6 cables are terminated with environmentally sealed F-connectors.
As mentioned above, the modem supplies the DC voltage necessary to power the LNB.
The IDU supplies 48 volts DC to the antenna's OutDoor Unit (ODU) through an RG6 (or
equivalent) cable terminated with TNC connectors.
Communication between the IDU and the ODU are carried over the antenna's power
cable utilizing Bluetooth Protocol. This cable is terminated with TNC connectors.
8.1.4 - Sensors
The system is designed with an onboard GPS receiver to determine antenna location.
These coordinates are utilized when calculating initial elevation and skew angles.
The pointing angles are also compensated by pitch and roll sensors.
For heading information the system has an onboard compass which is used to establish
initial azimuth calculation.
In some occasions compass calibration may be impractical or magnetic deviation may
require an override of the automatic compass information. The software provides for
input of manual heading information. This override is called a Fixed Heading input.
