Iridium AD510-4 Passive Antenna – N-Type Terminal (Includes ARA-AW2446000 Mount)

The Iridium AD510-4 (SKU: AST-AW2446000 / MPN: AD510-4) is a professional-grade passive Iridium antenna designed for use with the Iridium satellite network. It is built for permanent external mounting in harsh, marine, and remote environments where consistent satellite signal performance is required.

Ideal for fixed-site, maritime, and industrial deployments, the AD510-4 uses a Right-Hand Circular Polarised (RHCP) radiation pattern across the Iridium band and is designed to be installed with a clear, unobstructed view of the sky (horizon to horizon) for best results.

Key Product Features

• Build Quality: 4mm GRP/polyester radome with a hard-anodised aluminium base engineered for mechanical resilience and corrosion resistance.
• Environmental Rating: Operating temperature range specified at -40°C to +85°C (harsh-environment capable).
• Technology Type: Passive antenna (no external power required).
• Network / System Optimisation: Designed to operate over Iridium L-band / Iridium frequency band (Iridium network use).
• Installation Flexibility: Ground-plane independent (“free air” mounting); mount to a mast/pole/spar for external use.

What’s Included

• Iridium AD510-4 Passive Antenna (N-Type version)
• Mount bracket: ARA-AW2446000 (as supplied with this kit)
• Coaxial cable: Not stated as included with this kit (select to suit installation)

Mounting & Installation

This product supports flexible installation and is suitable for:

• Mounting to vertical or horizontal masts/poles/spars
• Support structures up to 60mm diameter (using supplied mounting hardware on comparable AD510-series brackets)
• Marine rails and industrial frameworks where a clear sky view can be achieved

Installation Tip: Passive Iridium antennas are commonly specified with a maximum practical coax run of around 20m on standard passive setups; for longer runs, an active Iridium antenna solution is typically recommended. Use low-loss coax and quality terminations to minimise attenuation (the retailer listing recommends low-loss cable such as LMR-400 for performance).

Technical Specifications

• Frequency Range: 1616 MHz – 1626.5 MHz (Iridium Network); some AD510-series documentation lists 1610–1630 MHz
• Connector Type: N-Type Female (AD510-4 variant)
• Impedance: 50 Ohms
• VSWR: Less than 1.5:1 (retailer listing); some AD510-series documentation lists VSWR < 2:1
• Polarisation: Right Hand Circular (RHCP)
• Dimensions: 100mm (height) x 87mm (max diameter)
• Weight: Approx. 1.0 kg (antenna + bracket); retailer shipping/packaged weight shown as 1,200g
• Materials: 4mm GRP/polyester radome + hard-anodised aluminium base

Compatibility

This product is compatible with the following equipment and systems:

• Iridium satellite handsets including 9555, 9575 Extreme, 9505, and 9505A (via appropriate cabling/interface)
• Iridium fixed-site / docking terminal deployments where an external Iridium antenna is required (via appropriate interface/cabling)
• Iridium M2M / data terminal deployments that accept an external Iridium-band antenna connection (verify connector/cable requirements)

Compatibility Note: Install with an unobstructed sky view for best Iridium performance. Ensure connected equipment operates within the Iridium band and avoid introducing spurious emissions from non-compliant signal sources (manufacturer guidance exists for AD510-series use with compliant Iridium systems).

Ideal Applications

• Maritime Satphone Installations: Mount on a yacht/boat mast rail so the Iridium handset or docking station below deck gets a more reliable satellite link with fewer dropouts.
• Remote Site Safety Comms: Fit on a site cabin or control hut at remote construction/mining sites to support emergency calling when cellular coverage is unreliable or absent.
• Vehicle or Expedition Base Camp: Mount to a fixed pole at a temporary base camp (surveying, film, research) to improve call stability vs. handheld-only use in challenging terrain.
• Industrial Fixed Installations: Use on permanently installed Iridium fixed terminals where harsh weather resistance and corrosion protection are important.

Certifications & Compliance

• Designed for operation over the Iridium frequency band / Iridium network use
• Manufacturer guidance for AD510-series references operation within harmonised Iridium band requirements (e.g., directive-era spectrum compliance guidance) and avoiding harmful interference sources
• Harsh-environment construction intended for external mounting in marine/industrial conditions
