Saab DGNSS Antenna MGL-5 (30 Db , TNC-F), Excl. Cable (7000 000-555)

Saab DGNSS Antenna MGL-5 (30 Db , TNC-F), Excl. Cable (7000 000-555)

In the context of Saab’s bridge navigation products, the MGL-5 is frequently associated with DGNSS (Differential GNSS) operation, where the navigation system uses correction data (for example from beacon-based services and/or external correction inputs) to improve positioning integrity and accuracy relative to unaugmented GNSS.

Design and Features

Combined GNSS / Beacon Antenna Role

An important characteristic of the MGL-5 in Saab documentation is its identification as a “DGNSS Antenna (Combined GNSS / Beacon)”. This wording indicates that the antenna is intended for DGNSS configurations that incorporate GNSS satellite reception together with beacon-oriented correction reception in systems that use beacon services or beacon correction inputs as part of the overall DGNSS solution.

Active Antenna With 30 dB Specification

Multiple reseller listings describe the MGL-5 as a 30 dB antenna. In marine GNSS installations, a gain figure of this type is commonly associated with an active antenna design (with a built-in low-noise amplifier), which can help maintain usable signal levels across real-world vessel cable runs and RF environments.

TNC-F Connector Standard

The MGL-5 is widely advertised with a TNC-F connector. Threaded TNC connectors are common in marine RF installations due to secure mechanical coupling and predictable service behavior in vibration-prone environments.

“Excluding Cable” Packaging

The “Excl. Cable” designation is a practical installation feature. By shipping without coax, the antenna can be paired with a cable type and length suited to the vessel (mast routing, deck glands, lightning protection layout, and separation requirements from other RF systems).

Technology and Specifications

Identification

• Product: Saab DGNSS Antenna MGL-5

• Saab part number: 7000 000-555

• Listed gain: 30 dB

• Connector: TNC-F

• Cable: Not included (“Excl. Cable”)

Environmental Installation Category (IEC 60945 Context)

In an R6 Navigation System manual excerpt, the MGL-5 is listed as “Exposed” in the IEC 60945 installation category table (i.e., suitable for external installation conditions typical of antenna placements).

System Association: Saab R6 NAV DGNSS Kits

The MGL-5 is commonly included in complete Saab navigation kits. For example, a product listing for Saab R6 NAV DGNSS System MkII (7001 000-731) enumerates the MGL-5 DGNSS antenna excl. cable (7000 000-555) as part of the kit bill of materials.

This is significant operationally: many shipowners and yards prefer a kit configuration because it ensures the antenna model aligns with the intended sensor and documentation package.

Correction Inputs in R6 NAV Context

Public product descriptions of the R6 NAV DGNSS system family reference support for correction inputs such as IALA and RTCM (input types), reinforcing the DGNSS operating environment that the MGL-5 is designed to support.

Applications and Use Cases

1) DGNSS Navigation Receiver Installations on Commercial Vessels

The MGL-5 is typically deployed as the antenna component in professional maritime DGNSS navigation installations—particularly where bridge systems depend on consistent, standards-aligned position outputs (for ECDIS, radar overlays, conning, logging, and alarm management workflows).

2) Replacement Antenna for Existing Saab R5/R6 NAV Installations

Because 7000 000-555 is consistently referenced by part number across reseller catalogs and manuals, it is frequently selected as a like-for-like replacement for vessels maintaining configuration continuity during service events or refits.

3) Shipyard and Fleet Standardization

Fleet operators often standardize antenna models to simplify:

• spares inventory,

• installation drawings,

• service procedures,

• and documentation across sister vessels.

The fact that MGL-5 appears both as a standalone product and inside complete navigation kits supports this “standard part” role.

Advantages / Benefits

Purpose-Built for DGNSS System Context

The MGL-5 is explicitly labeled in Saab documentation as a Combined GNSS / Beacon antenna, indicating that it is intended for DGNSS configurations rather than being a generic GNSS-only antenna.

Installation Flexibility Through Cable Exclusion

By shipping without cable, the antenna can be installed with vessel-appropriate coax length and routing strategy—often necessary on larger ships where antenna-to-receiver cable runs may be long.

Marine-Robust Connector Choice

The TNC-F connector is widely recognized in marine RF work as a robust, threaded interface, supporting reliability and serviceability.

Common Inclusion in Complete DGNSS System Kits

As shown in kit BOM listings, the MGL-5 is bundled into complete R6 NAV DGNSS solutions, reducing procurement risk and helping ensure component compatibility.

FAQ Section

What is the Saab DGNSS Antenna MGL-5 (7000 000-555)?

It is a marine DGNSS antenna identified as 30 dB, TNC-F, supplied without cable, and used in Saab navigation system configurations—particularly DGNSS deployments.

How does the Saab MGL-5 antenna work?

In Saab documentation, the MGL-5 is described as a Combined GNSS / Beacon antenna, meaning it supports antenna operation in DGNSS systems that incorporate GNSS positioning with beacon-oriented correction reception/operation as part of the overall navigation solution.

Why is the MGL-5 important in maritime navigation?

For DGNSS configurations, the antenna is a critical front-end component enabling the navigation system to maintain robust reception and support correction-driven operation. It is also commonly included in complete Saab R6 NAV DGNSS system kits, supporting standardized shipyard installations.

What are the benefits of the MGL-5 antenna?

Key benefits include the 30 dB active-antenna specification (as listed), the TNC-F marine connector, and its role as a Combined GNSS / Beacon antenna option referenced in Saab R6 NAV documentation.

Does the MGL-5 include an antenna cable?

No. Listings explicitly state “Excl. Cable,” meaning the coaxial cable must be ordered separately to match the vessel’s installation requirements.

Summary

The Saab DGNSS Antenna MGL-5 (7000 000-555) is a 30 dB, TNC-F, cable-excluded antenna used in Saab’s DGNSS navigation ecosystem and documented as a Combined GNSS / Beacon antenna suitable for exposed marine installation conditions. Commonly included in complete R6 NAV DGNSS system kits and widely stocked by maritime electronics resellers, it serves as a standardized antenna option for professional bridge navigation installations where DGNSS operation and consistent documentation alignment are priorities.
