AD-22/F — High Gain Log-Periodic Dipole Antenna (1-6 GHz)

Overview

The AD-22/F is a high-gain log-periodic dipole antenna (LPDA) operating across the 1000 to 6000 MHz frequency range. Enclosed in a robust plastic radome, it features a central boom and 30 brass dipoles designed for tactical, transportable, or stationary base station operations.

Technical Summary

Operational Use Cases

• Jamming: Handles up to 120 W CW power for high-intensity electronic attack applications.
• Radio Monitoring: Provides wideband directional coverage for signal detection and spectrum observation.
• EMC Applications: Supports broad frequency sweeping and directed emissions for electromagnetic compatibility tasks.

Deployment Environments

This antenna is engineered for versatility across fixed site and tactical platforms. The durable plastic enclosure protects the active brass elements, supporting deployments in transportable configurations or long-term stationary base stations.

Performance Metrics

• Directional Gain: 9 to 11 dBi
• Power Handling: 120 W CW maximum
• Frequency Coverage: Continuous bandwidth from 1 GHz to 6 GHz

Setup & Portability

An integrated antenna support is located on the end of the boom to facilitate installation. Verify that your mounting mast has an outer diameter between 26 mm (1 inch) and 60 mm (2 inches) to ensure a secure fit with the support bracket.

FAQs

• How does a log-periodic dipole array (LPDA) produce a directional beam? An LPDA utilizes appropriately-sized dipole elements spaced along a boom to direct radio frequency energy. This arrangement concentrates the signal into a directional pattern across a wide frequency range.
• Why is it important to match antenna polarization? Antennas with the same polarization state provide the most efficient transmission and reception path. For optimal performance, a receiving antenna must be aligned with the linear orientation of the incoming electromagnetic wave.
• What is the operational advantage of elevating a directional antenna? Raising the antenna on a mast helps establish a clear line of sight over local terrain and obstacles. This elevation maximizes effective power downrange and increases necessary operational standoff distance.
• 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).
