Antenna and Feed Assembly

Incoming signals from the satellite are int

ercepted by the antenna
reflector ("dish") and focused into the feed assembly. The feed
assembly collects receive signals and passes them to the LNB.

The anten

na geometry is termed an Offset Feed Parabola, with the

beam (satellite direction) typically orie

nted 22.6o above a line
perpendicular to the antenna face, as shown above. The antenna
mount allows the antenna to be pointed toward the satellite by pivoting
around the mounting mast (azimuth) and by tilting about the mounting
head (elevation). The entire

Antenna Assembly can be rotated about

the feed axis to set polarization.
Note that it is not a rule that an antenna offset is 22.6o. Refer to the

documentation that accompanies the antenna for the actual offset
specification.

LNB

The LNB provides the

low noise amplification and down conversion
from Ku-band or C-band to L-Band. The down converted signals are
then routed to the RCST via coaxial cable. Based on the satellite
downlink frequency bands, the LNB is available to receive the
frequencies as spe

cified below.

BUC

The BUC (Block up converter) accepts transmit signals from the
RCST and provides up conversion to the satellite uplink frequency and
transmits them to the satellite

.

For the StarPro1

ODU, the BUC includes a Solid State Power Amplifier available as Ku-

Band

transceivers for .5-, 1-, 2-, or 4-Watt operation and as C-Band transceivers for 2

- and 5-

Watt

operation. The RCST provides a 24VDC source to power these units. For the 4-

Watt Ku-ba

nd
and 5-Watt C-band units, the RCST is equipped with an external power supply adapter to satisfy
the additional power requirement.

Return Channel Satellite Terminal (RCST)
The StarPro1 RC

ST combines a DVB receiver, a burst MF-TDMA modulator, and a terrestrial

traffic interface on a single integrated circuit board.

Proprietary

The RCST terrestrial interface is a standard 10/100BaseT. The TCP Acceleration processing
engine is built into the RCST soft

ware. The maximum aggregate TCP data transmission rate for

each RCST is 10Mbps.
The RCST comes with L-Band IF interfaces and can be rack-mounted. Depending upon the

satellite link requirements, the StarPro1 RCST is deployable in VSATs ranging from sub-met

er

0.96m/1-Watt Ku-band units to 2.4m/. 5-Watt C

A rack mounted RCST must occupy 3U space where the top 2U space is left empty as to ensure
adequate cooling. Less space can cause overheating and failure of the terminal.

Similarly, a tabletop mounted RCST requi

res the placement to be cool and well ventilated. No

other items may be resting on top of the unit to ensure adequate cooling.
