Inmarsat Beam Passive SMA/TNC Cable Kit - 20m/65.6ft (ISD937)

The Inmarsat Beam Passive SMA/TNC Cable Kit - 20m/65.6ft (ISD937) 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 ISD937 is a high-performance 20-metre (66 feet) antenna cable kit specifically engineered for fixed-site passive satellite communication. This kit provides the necessary reach for installations where the antenna must be placed at a significant distance from the docking station, such as on a rooftop or a dedicated mast, without the need for active signal amplification. It ensures high-fidelity signal transmission for stationary users of the Inmarsat GSPS network.

Key Product Features

• Extended Passive Reach: Offers a 20m run, providing greater flexibility for antenna placement in fixed-site environments.
• Dual Cable Configuration: The kit includes both a 20m Inmarsat satellite antenna cable and a 20m GPS antenna cable.
• Pre-Terminated Precision: Factory-fitted with high-quality SMA and TNC connectors to ensure a secure and low-loss connection.
• Low-Loss Design: Features a thick 10.3mm satellite cable diameter to maintain signal integrity over the 66-foot distance.
• Fixed-Site Specialised: Specifically built for permanent installations in commercial and industrial settings.

What’s Included

• 1x 20m (65.6ft) Passive Inmarsat Satellite Cable (TNC to SMA)
• 1x 20m (65.6ft) Passive GPS Cable (SMA to SMA)

Installation & Usage

The ISD937 kit is intended for professional fixed-site deployment where the antenna and terminal are separated by a medium distance.

• Route the 20m cables through protected conduits or along cable trays, observing the single bend radius of 25.4mm for the satellite cable.
• Connect the TNC end to the antenna and the SMA end to the satellite port on the docking station.
• Ensure the GPS cable is connected to the corresponding SMA ports at both ends of the system.
• This cable is strictly for fixed, stationary land installations and must not be used in mobile (vehicular or maritime) applications.

Usage Tip: Due to the passive nature of this kit, it is critical to ensure all connectors are hand-tightened and free of debris to maintain optimal signal strength over the 20-metre run.
