OPTIM MICROWAVE INC S40_DK-003 02468 KU BAND FEED FOR SEATEL ANTENNA MADE IN USA

Product Description: OPTIM MICROWAVE INC S40_DK-003 / 02468

Product Name: Ku-Band Feed Horn Assembly for Sea Tel Antennas
Model Number: S40_DK-003 / P/N 02468
Manufacturer: OPTIM MICROWAVE INC

Overview:
The S40_DK-003 (also identified as part number 02468) is a high-performance, Ku-Band feed horn and orthomode transducer (OMT) assembly designed specifically as a replacement or upgrade component for Sea Tel marine stabilized satellite antenna systems. This unit is critical for receiving and transmitting satellite signals in the Ku frequency band, enabling broadband internet, television, and communication services at sea.

Primary Application:
This feed is engineered to be compatible with various Sea Tel maritime VSAT (Very Small Aperture Terminal) antennas, such as the Sea Tel 97xx, 40xx, or similar series models that utilize a Ku-band feed of this form factor. It is a key SEO (Satellite Earth Station – Outdoor) product for vessel satellite communication systems.

Key Features & Specifications:

• Frequency Band: Ku-Band. Specifically designed for satellite communication frequencies (e.g., ~10.7-12.75 GHz for Rx, ~13.75-14.5 GHz for Tx, depending on specific model configuration).

• Polarization: Typically supports Dual Linear (Vertical and Horizontal) or Circular polarization, controlled by the associated antenna system’s BUC (Block Upconverter) and LNB (Low-Noise Block Downconverter).

• Component Integration: Integrates a feed horn and an Orthomode Transducer (OMT) into a single assembly. The OMT separates the transmitted and received signals.

• Waveguide Interface: Features standard rectangular waveguide ports (likely CPR-137G or equivalent) for connection to the antenna’s LNB (for reception) and BUC (for transmission).

• Scalar Ring / Feed Cone: Includes an integrated scalar ring or corrugated feed design to optimize illumination of the parabolic reflector, maximizing gain and minimizing spillover and side lobes.

• Robust Construction: Built for the harsh marine environment, with materials and coatings that provide resistance to saltwater corrosion and UV radiation.

• Precision Alignment: Engineered for precise focal point alignment on compatible Sea Tel antenna reflectors to ensure optimal system performance (G/T and EIRP figures).

Purpose & Benefits:

• Direct Replacement: Serves as a reliable replacement part for worn or damaged feeds in existing Sea Tel installations, restoring system performance.

• Performance Maintenance: Ensures the antenna system maintains optimal signal strength, quality, and link stability.

• System Compatibility: Designed as a form-fit-function equivalent to original Sea Tel components, ensuring seamless integration with the antenna’s servo and RF systems.

Typical Use Case:
This component is used by marine electronics technicians, VSAT service providers, or vessel IT staff to repair or maintain the satellite communication system on yachts, commercial ships, offshore rigs, and cruise lines equipped with a compatible Sea Tel antenna.
