Inmarsat Beam Passive SMA/TNC Cable Kit - 30m/98ft (ISD939)

The Inmarsat Beam Passive SMA/TNC Cable Kit - 30m/98ft (ISD939) is a professional-grade product designed for reliable performance in business-critical and industrial environments. Built to meet commercial standards, it is suitable for daily operational use.

The ISD939 is a high-performance 30-metre (98.4 feet) antenna cable kit specifically engineered for fixed-site passive satellite communication. This kit is designed for expansive stationary installations where the antenna must be placed at a significant distance from the docking station, such as on high masts or distant rooftops of large industrial complexes. To ensure signal integrity over nearly 100 feet while maintaining ease of connection, the kit includes specialised fly lead adaptors.

Key Product Features

• Extended Passive Reach: Provides a 30m run to support large-scale fixed-site infrastructure.
• Integrated Fly Lead: Includes a 50cm TNC(f) to SMA(m) adaptor to facilitate easier connection of the heavy-gauge satellite cable to the docking station.
• Dual Cable System: The kit contains both a 30m Inmarsat satellite antenna cable and a 30m GPS antenna cable.
• Industrial Build: Features a thick 12.7mm (0.5 inch) satellite cable diameter to minimise signal attenuation over long passive runs.
• Pre-Terminated Precision: Factory-fitted with high-quality TNC and SMA connectors for a secure, professional interface.

What’s Included

• 1x 29.5m (96.8ft) Passive Inmarsat Satellite Cable (TNC-m to TNC-m)
• 1x 30m (98.4ft) Passive GPS Cable (SMA-m to SMA-m)
• 1x 50cm (1.64ft) Fly Lead Adaptor (TNC-f to SMA-m)

Installation & Usage

The ISD939 kit is intended for professional fixed-site deployment where significant cable length is required.

• Utilise the 50cm fly lead adaptor to connect the main 12.7mm satellite cable to your docking station; this prevents mechanical stress on the terminal's SMA port.
• Route the cables through appropriate industrial conduits, ensuring you respect the 32mm single bend radius for the main satellite line.
• Due to the weight of the kit (6.1 kg / 13.45 lbs), ensure all mounting hardware and cable supports are rated for industrial loads.
• This cable is strictly for fixed, stationary land installations and must not be used in maritime or vehicular applications.

Usage Tip: For specialised projects, passive cable kits can be custom-ordered in lengths up to 50m. Please allow 4-6 weeks for such custom configurations.

Key Capabilities

• Enables satellite connectivity for large-scale remote facilities and multi-story operations centres.
• Maintains a reliable GNSS (GPS) L1 signal for precise fixed-site monitoring over long distances.
• Optimised for the specific frequency requirements of the Inmarsat GSPS network.
• Built to withstand permanent outdoor exposure when installed with the ISD700 antenna.

Compatibility

The ISD939 cable kit is ONLY for use with the Beam Inmarsat ISD700 Passive Antenna.

Compatibility Note: This cable is NOT compatible with active antennas such as the ISD710, ISD715, or ISD720.

Ideal Applications

• Large-scale remote field offices and industrial base stations.
• Multi-story industrial complexes require mast-mounted antennas.
• Fixed-site government, military, and emergency response infrastructure.
• High-interference industrial zones require thick-shielded, long-run cabling.
