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.
