Inmarsat Beam Active SMA/TNC Cable Kit - 90m/295.3ft (ISD946)

The Inmarsat Beam Active SMA/TNC Cable Kit - 90m/295.3ft (ISD946) 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 ISD946 is an elite, ultra-long 90-metre (295.3 feet) antenna cable kit engineered for the most demanding satellite communication installations. This industrial-strength solution is designed for the world's largest maritime vessels, extensive fixed industrial sites, and deep-deck installations where the distance between the docking station and the antenna requires specialised, heavy-duty cabling. To maintain signal integrity and manage the mechanical handling of such massive cabling, the kit includes precision adaptor fly leads to bridge the high-gauge main cable to the terminal equipment.

Key Product Features

• Extreme Distance Solution: Provides a massive 90m total run, specifically for the largest maritime and industrial infrastructure projects.
• Specialised Fly Leads: Includes two adaptor leads (50cm and 150cm) to allow the heavy 28mm main cable to interface safely with SMA/TNC ports.
• Active Signal Support: Fully optimised to deliver the DC voltage necessary to power internal amplifiers in Beam active antenna models across the entire 295-foot span.
• Industrial Shielding: Features a thick 28mm satellite cable diameter to ensure minimal signal attenuation and maximum protection against interference.
• Pre-Terminated Reliability: Factory-fitted with high-quality N(m) and SMA connectors for a secure, moisture-resistant connection.

What’s Included

• 1x 88.5m (290.3ft) Active Inmarsat Satellite Cable (N-m to N-m)
• 1x 90m (295.3ft) 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 ISD946 kit is intended for expert professional installation where structural constraints require an extreme cable run.

• 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 a 25.5mm radius for the GPS cable during routing.
• Due to the significant weight (46 kg / 101.4 lbs), this product must be shipped on a pallet and requires industrial-rated cable supports.
• Ensure all N-type connectors are properly seated and hand-tightened to maintain environmental integrity.

Usage Tip: Beam active cable kits can be specially ordered in custom lengths up to 100m. Please allow for a 3-4 week lead time for such custom configurations.
