5 1.1 Technical Specifications TRANSMIT / RECEIVE ~ NEW SERIES 1385 ~ 3.8m VSAT ANTENNA Key Features UPGRADED INTEGRAL RIB DESIGN FOR HIGHER FREQUENCY OPERATION. INCREASED STRENGTH FOR HEAVIER RADIO AND ODU EQUIPMENT LOADS. HIGHER PRECISION ASSEMBLY AND ALIGNMENT FROM AUTOMATED MANUFACTURING PROCESSES. FIELD FRIENDLY INSTALLATION WITHOUT REQUIREMENT FOR SPECIALIZED TOOLS. ANTI-ICE CAPABILITY FOR USE IN COLD CLIMATE AND ARCTIC ENVIRONMENTAL CONDITIONS. OPTIMIZED, 4-PIECE REFLECTOR DESIGN FOR MAXIMUM SHIPPING EFFICIENCIES. UPGRADABLE FOR HIGH XPD PERFORMANCE. Description The new series 1385 ~ 3.8m antenna has been designed to provide a reliable, long-life and trouble free antenna solution for demanding applications in the primary VSAT communications bands. Enhancements to this antenna design have improved the structural stability and surface tolerances of the reflector, offering growth potential for reliable communications up to Ka-band. C-band Azimuth, +/- 1 deg, Coverage (Tx) Band The antenna has been designed to meet the performance requirements of the major satellite service providers and regulatory agencies. The mechanical design has been optimized for high efficiency packaging to reduce shipping costs. Material selections for the reflector significantly reduce the risk for shipping damage when compared to metal reflector solutions. Factory pre-assembly of critical components eliminates the requirement for complex assembly procedures in the field. Ku-band Azimuth, +/- 1 deg, Coverage (Tx) Band CMR Rev 4-28 Page 4

76 5. Test Equipment Details 5.1 General Information SATCOM Technologies / Prodelin Antenna Test Facility is located 5km (3 miles) East of Maiden, NC and approximately 16km (1 Miles) South-southeast of Prodelin main office in Newton, NC. We are located 61km (38 Miles) from Charlotte International Airport and 149km (9 miles) from Piedmont Triad International Airport in Greensboro, NC. The antenna range can test a multitude of frequencies between 8 MHz and 3.GHz, and antennas up to 4.5 meters in diameter. Testing is accomplished over a test path between a fixed transmit tower location and a fixed receive tower location, separated by a distance of Meters ( feet). Transmit and receive tower heights are meters (57.11 feet) above ground level. Using directional antennas, an unmodulated carrier wave (CW) test signal(s) are transmitted from the source tower location toward the receive tower location. The signal is then received and interpreted by the sophisticated Orbit F/R959 Antenna Measurement System. Data is digitally recorded and many options of data analysis and presentation are possible using the Orbit F/R DataPro and GD specific software. 5.2 Test range specifics: Range Length C/L Tx Source Antenna AGL C/L AUT Mounting Positioner AGL Meters ( Feet) Meters (57.11 Feet) Meters (57.88 Feet) Test zone: Frequency range.8-3.
