KU-BAND DIAMOND ANTENNA 115477-6 REVC 2011 08 1/49-845-0 WAVEGUIDE ROTARY JOINT

This is a high-performance Ku-Band antenna assembly designed for applications requiring continuous 360-degree rotation while maintaining signal integrity. The core antenna element utilizes a proprietary "Diamond" configuration, optimized for enhanced performance in the Ku-Band spectrum (typical applications include satellite communication uplinks/downlinks, radar, or tracking systems).

The assembly integrally incorporates a precision waveguide rotary joint. This critical component allows the transmission of RF power and signals from a stationary input port to the rotating antenna aperture without interruption, minimizing insertion loss and VSWR (Voltage Standing Wave Ratio) across the full range of rotation.

Key features likely include:

  • Frequency Range: Optimized for a specific segment within the Ku-Band (e.g., 13.75-14.5 GHz Tx, 10.95-12.75 GHz Rx).

  • Polarization: Likely linear (vertical/horizontal) or dual-polarized capability.

  • Gain: Dependent on the antenna's diameter/aperture (not specified in string).

  • Waveguide Interface: Standard rectangular waveguide (e.g., WR-75, WR-62) specified by the "SEO" or drawing number.

  • Robust Construction: Built to meet stringent environmental standards (vibration, shock, temperature, moisture) typical for aerospace, military, or maritime platforms.

  • Revision Status: This is the third major design iteration (REVC), incorporating engineering improvements up to August 2011.

Typical Applications:

  • Mobile satellite communication (SATCOM) terminals on ships, aircraft, or ground vehicles.

  • Radar systems requiring rotating feeds.

  • Tactical data link antennas.

  • Satellite tracking ground stations.

Part Number Analysis:

  • KU-BAND DIAMOND ANTENNA: The primary product is an antenna.

    • Ku-Band: Operating in the 12-18 GHz frequency range, commonly used for satellite communications, broadcasting (DBS), and radar.

    • Diamond Antenna: Likely refers to a proprietary design or shape (possibly a "diamond" or rhombus-shaped element/array) known for specific performance characteristics like wide bandwidth or dual-polarization.

  • 115477-6: The base part number.

  • REVC: Revision level "C", indicating this is the third major revision of the design.

  • 2011 08: Likely a date code (Year 2011, Month 08 - August).

  • 1/49-845-0: Possibly a drawing number, contract number, or related assembly identifier.

  • WAVEGUIDE ROTARY JOINT: A critical sub-component. This device allows microwave energy (in waveguide form) to pass from a stationary feed to a rotating antenna (like a tracking dish) without signal loss or leakage. It's what enables the antenna to spin continuously.
