Product catalog summary
Overview
ORBIT's Conical Scan feed system offers a dual-band solution for telemetry communication, supporting both S and C bands. This system is designed for simultaneous operation in these frequency bands, addressing the growing use of C-band frequencies alongside the traditional S band. The feed system is compact, making it ideal for tactical and field telemetry operations requiring quick deployment and transportability.
Key Features
  • Efficient reflector illumination for antennas as small as 1.2 meters (4 feet).
  • Simultaneous support for S & C bands with high G/T performance.
  • Wide-range tracking capabilities with auto-tracking using the Conical Scan technique.
  • Single feed supporting dual bands with a low axial ratio.
Technical Specifications
  • Frequency Range: S Band (2185-2485 MHz), C Band (5091-5250 MHz).
  • Scan Rate: 50 Hz (3000 RPM).
  • F/D Ratio: 0.37-0.45.
  • Polarization: Dual Linear (V&H) or Dual Circular (LHCP & RHCP).
  • VSWR: <2.0:1 on output ports.
  • Axial Ratio: 2.0 dB Max.
  • Size: Length: 23.6” (600 mm), Diameter: 7.1” (180 mm).
  • Pressurization: Dry air at 5 psi max.
System Performance
  • Minimum Gain [dBi]:
    Reflector Diameter: 1.2 m / 4 ft - S Band: 3, C Band: 9.3
    Reflector Diameter: 3 m / 9.8 ft - S Band: 11, C Band: 17.3
    Reflector Diameter: 4.5 m / 14.7 ft - S Band: 14.5, C Band: 20.8
Environmental Specifications
  • Altitude: Operational up to 6.3 km (20,000 ft), Storage up to 12.6 km (40,000 ft).
  • Temperature: Operational: -20°C to +55°C (-4°F to +130°F), Shipping: -40°C to +70°C (-40°F to +158°F).
  • Rainfall: < 100 mm/hour (4”/hour).
  • Humidity: 0-100% relative.
  • Transportation: The feed should be kept in ORBIT’s case during transport.

AL-1100C-SC S&C Band, Conical Scan, Auto-Tracking Feed Typical Applications Aeronautical Test Telemetry The World's Smallest High-Performance Dual Band S&C Feed Solution ORBIT’s new Conical Scan feed system provides a breakthrough solution for simultaneous operation in multiple telemetry communication frequency bands. This solution was developed to address the telemetry market’s growing adoption of C-band frequencies – in parallel to the widely used S band. Based on its concentric coaxial cavity technology, ORBIT can offer a single feed supporting both bands for any antenna reflector size. ORBIT’s innovative Conical Scan feed can simultaneously receive S and C bands and auto-track any of those bands per customer configuration. With the smallest footprint on the market, the S&C band feed uniquely addresses the needs of tactical forces and field telemetry operations for fast deployment and transportability.  Efficient reflector illumination small as 1.2 meters (4’)  Simultaneous support of S & C bands  High G/T performance  Wide-range tracking capabilities  Auto-tracking using Conical Scan technique  Single feed supporting two band
