Inmarsat Beam Active SMA/TNC Cable Kit - 100m/328.1ft (ISD947)

The Inmarsat Beam Active SMA/TNC Cable Kit - 100m/328.1ft (ISD947) 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 ISD947 represents the maximum standard length for Beam's active antenna cable kits, providing a 100-metre (328.1 feet) run for the most expansive satellite communication deployments. This kit is engineered for ultra-large maritime vessels, high-capacity offshore platforms, and massive industrial complexes where the distance between the docking station and the antenna requires a highly specialised, ultra-low-loss cabling solution. To ensure signal integrity and manageable connectivity, the kit includes precision adaptor fly leads to bridge the industrial-grade main cable to terminal equipment.

Key Product Features

• Maximum Range Deployment: Provides a 100m total run, the longest standard configuration available for Inmarsat GSPS active systems.
• Modular Adaptor System: Includes two fly lead adaptors (50cm and 150cm) to safely interface the heavy 28mm main cable with SMA and TNC terminal ports.
• Active Power Management: Optimised to deliver the DC voltage necessary to power internal amplifiers in Beam active antenna models across the full 328-foot span.
• Ultra-Low Loss Construction: Features a thick 28mm satellite cable diameter to ensure minimal signal attenuation at extreme distances.
• Pre-Terminated Reliability: Factory-fitted with high-quality N(m) and SMA connectors for a secure, industrial-strength connection.

What’s Included

• 1x 98m (321.5ft) Active Inmarsat Satellite Cable (N-m to N-m)
• 1x 100m (328.1ft) Active GPS Cable (SMA-m to SMA-m)
• 1x 50cm (1.64ft) Fly Lead Adaptor (N-f to SMA-m)
• 1x 150cm (4.92ft) Fly Lead Adaptor (N-f to TNC-m)

Installation & Usage

The ISD947 kit is intended for expert professional installation in environments with extreme structural cable-run requirements.

• Use the provided fly-lead adaptors at both ends of the main satellite cable to facilitate connection to the docking station and antenna; this prevents mechanical stress on the terminal ports.
• Strictly observe a 120mm single-bend radius for the main satellite cable and 25.51mm for the GPS cable during installation.
• Due to the extreme weight (50 kg / 110.23 lbs), this product must be shipped on a pallet and requires industrial-rated cable supports.
• Ensure all N-type and SMA connectors are properly seated and hand-tightened to maintain environmental integrity.

Usage Tip: This cable kit is designed exclusively for active antennas. It is not compatible with passive antennas such as the ISD700, as active antennas require the power-handling capabilities provided by this cable type.
