AD-22/C — VHF/UHF/L-Band Log-Periodic Dipole Antenna

Overview

The AD-22/C is a transportable log-periodic dipole antenna designed to operate across the 80 to 1300 MHz frequency range. Covering VHF, UHF, and L-Band frequencies, it is primarily intended for EMC applications, radio monitoring, and similar tactical operations.

Technical Summary

• Frequency Range: 80 to 1300 MHz
• Antenna Type: Directional Log-Periodic Dipole Array (20 dipoles)
• Construction: Aluminum alloy boom with stainless steel screw joints
• Finish: UV-resistant polyurethane paint

Operational Use Cases

• EMC testing and verification
• Radio monitoring and spectrum analysis
• Transportable tactical communications

Deployment Environments

Engineered for transportable tactical deployments as well as permanent stationary installations. The UV-resistant polyurethane construction ensures durability across extended outdoor exposures.

Setup & Portability

The antenna is packaged in a specialized canvas transport bag to support tactical portability. It features a mounting console that facilitates rapid polarization changes between horizontal and vertical orientations.

Compatibility

The integrated mounting console is compatible with mast outer diameters ranging from 26 mm to 60 mm.

FAQs

• What is a directional antenna? A directional antenna radiates electromagnetic energy more effectively in specific directions than others. This design typically concentrates the radiation into one main lobe and several minor lobes, yielding higher gain in the favored direction.
• How does polarization matching affect signal reception? Polarization describes the physical orientation of an antenna's electric field as the wave travels through space. Using transmitting and receiving antennas with matching polarization states provides the most efficient transmission path.
• What should be verified when selecting an antenna based on gain? Review the azimuth and elevation radiation pattern graphs to confirm the energy distribution suits the intended coverage area. Higher gain generally concentrates radiation into a smaller beamwidth, requiring precise alignment.
• 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).
