Fixed satellite terminal
VT 120 Ka
The VT 120 Ka is a VSAT Terminal designed to provide instant access to satellite communications for any application that requires reliable and/or remote connectivity in a rugged environment. Ideally suited for industries such as Oil & Gas Exploration, Mining, Disaster Management, Construction, Mobile Offices, Emergency Services, Cellular Backhaul and many others. The VT 120 Ka can be mounted as a permanent installation. The pointing is entrusted to a very precise manual adjustment system. On this terminal many types of L-Band satellite modems can be used enabling users to access high throughput internet services via satellite and receive video broadcast services. VT 120 Ka can combine high performance and small size due to highly integrated components reducing the waveguide path and relevant losses such improving Tx power and Rx noise figure.
Key Features
• Integrated transceiver
• High Tx and Rx performance
• Low waveguide losses
• Solid state amplification technology
• L-Band IF interface
• 1.2m Full Carbon Epoxy single-piece parabolic
reflector
• Non-penetrating mounting pedestal or mast
mounting assembly
• IP 65 protection
• Guarantees the most severe environmental
conditions (operative -40°C +55°C)
Product overview
VT 120 Ka terminal is available in circular polarization and operates at 27.5GHz to 31.0GHz in uplink and at 17.7GHz to 20.2GHz in downlink. VT 120 Ka is a very flexible terminal with light weight, quick installation and high perfomances.
The basic components are:
• Antenna subsystem
• Transceiver
• IFL cables
Antenna subsystem
Functions
The main reflector is made of carbon-epoxy, consists of a single light parabola of 1.22 m, the reflecting surface is metallized to have very low ohmic losses. (A low cost reflector made of epoxy fiberglass is available. Maintaining the same surface shape and metallization process also ensures good performance) The structure is designed to accommodate up to three 140W TWTAs, in a 2+ redundancy system 1, and it is possible to have any redundancy in the LNA system plate. The main reflector consists of a single 1.22m lightweight reflector, made of fiberglass for easy alignment and packaging along with electrical precision, wind resistance and mechanical stability. It is organized in a single offset configuration for VT 120 Ka-Q.
The transceiver integrates the power supply with double isolation filter port and is directly connected with the 8W BUC. It is provided by a non-penetrating mounting system on pedestal and mast. This is based on an elevation mechanism with respect to azimuth, equipped with very precise positioning screws to ensure continuous fine adjustment during the alignment phase.
Transceiver
The transceiver is housed in a rugged, watertight (IP65) mechanical housing which is sealed against moisture, dust and rain, allowing the transceiver to withstand severe environmental conditions. The L band frequencies (950 ÷ 1650MHz For TX and TX) allow the installation of the most common modem models. External reference Can be loaded by GNSS Receive in case of blocked modem.
BUC
Two different power sizes are available: the 8 or 16 W terminal.
Born to be quick
• The light wheight
• The toolfree installation
• The quick installation, setup and pointing
• The availability of non penetrating platform as option
• The availability of transit case as option make this terminal a very good choice for replaceable terminal.
Thid is a very flexible product for any kind of application.
