Lars Thrane N Connector (male) for Coaxial Cable Ø4.9mm (91-101140)

The Lars Thrane 91-101140 N Connector is a precision-engineered RF component designed for termination of Ø4.9mm coaxial cables. This male N-type connector is a critical accessory for the LT-3100S GMDSS system, ensuring a high-quality, low-loss connection between the antenna unit and the control terminal.

Developed by Lars Thrane A/S, this connector is designed to withstand the demanding conditions of the maritime environment, providing a secure, weather-resistant interface for satellite communication frequencies.

Key Product Features

• Precision Fitting: Specifically designed for Ø4.9mm coaxial cables (such as the FF195 type), ensuring optimal mechanical and electrical alignment.
• Maritime Durability: Constructed with high-grade materials to resist corrosion, moisture ingress, and the physical stresses of sea-going vessels.
• Low Signal Loss: Maintains the high performance required for Iridium satellite network communications by minimising impedance mismatch and signal attenuation.
• Standard N-Type Interface: Features a standard male N connector thread, making it compatible with Lars Thrane antenna ports and standard maritime RF equipment.

What’s Included

The Lars Thrane 91-101140 package typically contains:

• 1x N Conn. (male) for Coaxial Cable Ø4.9mm

Installation & Usage

The 91-101140 connector is used for the field termination of satellite antenna cables:

• Preparation: Strip the Ø4.9mm coaxial cable to the required dimensions for N-type crimp or solder connectors.
• Assembly: Follow standard RF termination procedures to ensure the centre conductor and outer shield are properly seated and insulated.
• Tools: An appropriate crimping tool is required to secure the connector to the cable jacket and shield, ensuring a vibration-proof maritime installation.
• Protection: While designed for marine use, it is recommended to apply self-amalgamating tape or heat-shrink tubing over the connection if exposed directly to the elements on deck.

Ideal Applications

• Custom Cable Runs: Essential for technicians creating custom-length antenna cables for the LT-3100S system using Ø4.9mm wire.
• System Repairs: Serving as a high-quality replacement for damaged or corroded connectors on existing satellite antenna installations.
• Flexible Routing: Used in conjunction with Ø4.9mm cable, where tight bends or narrow conduits require a thinner, more flexible cable than the standard Ø10.3mm variants.
