Andrew Corporation 4.6 Meter Dual-Reflector Earth Station Antennas
Now communications system integrators and designers can bring their systems on line faster, more economically, and with superior performance with Andrew 4.6-meter Earth Station Antenna (ESA). In use around the world in high-density data, voice, communications networks, and broadcast applications, the Andrew 4.6-meter ESA features uniquely formed dual reflector Gregorian system coupled with close-tolerance manufacturing techniques. This combination provides extremely accurate surface contour, exceptionally high gain, superior efficiency, and closely controlled pattern characteristics.
Our wide selection of type-approved antennas speeds system commissioning. The Andrew 4.6 Type Approved ESA can be deployed in the field with minimal testing of G/T to become fully certified as an INTELSAT standard E-2, or F-1 station.
The 2-port C-Band Circular R/T feed system is manually field switchable from circular to linear polarization. The 48 inch (1219 mm) diameter by 24 inch (610 mm) equipment enclosure with doors allows hub mounting of LNA systems.
Andrew ESA’s provide maximum durability with minimal maintenance. The hot-dipped galvanized steel ground mount assembly ensures extended product life. Galvanized and stainless steel hardware maximize corrosion resistance. For cost effective system expansion, available modular equipment options include anti-icing equipment and pressurization systems. Microprocessor Steptrack Control and motorizable mount options are also available.
