ASE-DA20 20 Meter Dual Mode Vehicle Antenna (Iridium/GPS)

The ASE-DA20 (also marketed as the BSN-NAL ASE-DA20) is a high-performance, dual-mode vehicular antenna system designed to provide consistent satellite connectivity for users on the move. Specifically engineered by Applied Satellite Engineering (ASE), this antenna is optimised for professional installations where maintaining signal integrity over long distances is critical.

This dual-element antenna module integrates an Iridium L-band antenna element and a GPS antenna element into a single, ruggedised external housing. This integrated design reduces rooftop clutter and simplifies mounting compared to installing separate antennas for satellite voice/data and GPS positioning.

Key Product Features

• Extended 20-Meter Cable Run: Includes two 20-meter (66 ft) high-grade coax runs specifically designed to support flexible equipment placement in large vehicles or small vessels.
• Low-Loss LMR-600 Cabling: Utilises LMR-600 coaxial cables, which are widely recognised for their low-loss 50-ohm RF characteristics, ensuring stable performance and reduced attenuation over the 20m reach.
• Dual-Mode Functionality: Combines Iridium satellite and GPS (GNSS) into a single module, enabling simultaneous voice/data communication and precise location tracking.
• Vehicular & Marine Optimised: Designed to handle high-speed wind resistance and constant mechanical vibration, making it ideal for trucks, SUVs, service vehicles, and light marine craft.
• Simplified Mounting: Uses a single mounting footprint for two critical satellite services, reducing installation time and complexity for fleet rollouts.

What’s Included

The ASE-DA20 is a complete antenna solution package containing:

• 1x Integrated Dual Iridium/GPS Antenna Module
• 1x Mounting Fixture / Bracket
• 2x 20-Meter (66 ft) LMR-600 Cables (one for Iridium, one for GPS)
• Standard Mounting Hardware

Installation & Usage

The ASE-DA20 is designed for professional fixed-mount installation on a variety of mobile platforms:

• Antenna Placement: Mount the antenna at the highest available rigid point (roof, rail, or mast) to ensure a 360-degree, unobstructed view of the sky.
• Cable Routing: Route the two 20-meter LMR-600 cables to the Iridium docking station or terminal. The 66 ft reach allows docking electronics to be placed in secure equipment bays, cabins, or centre consoles.
• Versatility: While vehicle-focused, the format also suits semi-permanent remote sites, such as field shelters or mobile offices, where a 20m run is required.
