AD-18/G-2210 — Ultra Wideband Dipole Mobile Antenna

Overview

The AD-18/G-2210 is an ultra wideband dipole mobile antenna operating in the 225 to 1000 MHz frequency range. Designed for heavy-duty mobile applications, it features a ruggedized construction and an optional integrated active GPS L1 patch antenna for positioning capabilities.

Technical Summary

• Frequency Range: 225 to 1000 MHz
• Bands: VHF, UHF
• Antenna Type: Center-fed dipole (Omnidirectional)
• Ground Plane Requirement: Independent
• Optional Feature: Built-in active GPS L1 patch antenna (AD-18/G-2210G model)

Operational Use Cases

Primarily intended for heavy-duty vehicle and mobile applications requiring ultra wideband communications across VHF and UHF frequencies. The optional active GPS model supports platforms needing consolidated communication and location-tracking hardware.

Deployment Environments

Built to withstand demanding mechanical environments, the antenna base includes a built-in biconical stainless steel spring to absorb shocks and vibrations. The exterior is finished in UV-resistant military green polyurethane paint to endure harsh outdoor exposure.

Performance Metrics

Because it is electrically designed as a center-fed dipole, the antenna maintains its electrical characteristics independently of the mounting location or the presence of a ground plane.

Setup & Portability

The antenna consists of two main parts: a composite base and a 28 mm diameter fiberglass whip containing the radiating elements. The base mounts using four equally spaced holes arranged on a standard NATO 4.5-inch (114.3 mm) circle.

Compatibility

Compatible with standard NATO 4.5-inch (114.3 mm) mounting platforms. The ground-plane independent design allows for versatile placement across various structural surfaces without requiring a metal chassis counterpoise.

FAQs

• How does a ground-plane independent dipole differ from a monopole antenna? A dipole design does not require a metal mounting surface to form a counterpoise. This allows the antenna to operate without relying on the vehicle chassis to complete the electrical circuit.
• What radiation pattern characteristics are typical for standard omnidirectional antennas? Standard omnidirectional antennas typically radiate in a 360-degree azimuth pattern. Peak gain is frequently concentrated within 20 degrees above and below the horizon.
• What must be verified before installing this mobile vehicle antenna? Confirm that the platform can structurally support the assembly. Verify that the mounting surface accommodates the base interface, which requires a standard NATO 4.5-inch bolt circle configuration.
• Problems we solve: how do we narrow antenna choices? Balancing operating bands, coverage needs and mounting space can make antenna selection difficult. Share those constraints with Cyntony to compare candidate antennas and identify what needs manufacturer confirmation (Our process).
• Outcomes we deliver: what comes from working through the requirements? The practical outcome is a requirements-led set of product options to evaluate with Cyntony. Confirm performance, compatibility and any service scope for your configuration before selection (Our process).

Video Notes

A short video demonstrating the flexibility and shock absorption of the biconical stainless steel spring under vibration, as well as a brief walkthrough of the NATO 4.5-inch bolt installation process, would be useful for procurement and installation teams.
