AD-55/F — UHF Dipole Antenna

Overview

The AD-55/F is an ultra wideband manpack antenna designed for use with modern broadband software-defined radios (SDRs), jammers, and scanners. Its sleeve dipole center-fed configuration allows the antenna to operate effectively without requiring a ground plane.

Technical Summary

• Frequency Range: 1700 to 2600 MHz
• Gain: -1 to +2 dBi
• Power Handling: Up to 200 W CW
• Polarization: Vertical
• Design: Center-fed sleeve dipole

Operational Use Cases

Optimized for dynamic tactical scenarios, this antenna supports demanding applications including jamming, spectrum monitoring, and tactical communications.

Deployment Environments

The radiating element is fully enclosed in a rugged fiberglass radome, ensuring reliable operation in harsh military environments in accordance with MIL-STD-810G standards.

Performance Metrics

• Frequency Coverage: Continuous operation from 1700 to 2600 MHz (L-band and S-band).
• Power Capacity: Rated for a maximum continuous wave (CW) power of 200 W.
• Gain Performance: Maintains a gain profile between -1 and +2 dBi.

Setup & Portability

Configured for manpack platforms, the antenna features a ground-independent design, simplifying deployment since no external ground plane is necessary for proper operation.

Compatibility

Compatible with a wide range of RF electronics, including broadband software-defined radios, mobile jammers, and portable scanners.

FAQs

• Does a sleeve dipole antenna require a ground plane? No. A center-fed sleeve dipole functions independently and does not require a conductive ground plane or chassis to establish its impedance.
• What does vertical polarization mean for signal transmission? Vertical polarization indicates the electric field is oriented perpendicular to the surface. Ensure the connecting antennas share this orientation to maximize signal transfer and minimize mismatch loss.
• How should power handling be verified for jamming applications? Confirm the antenna's continuous wave (CW) rating meets or exceeds the maximum continuous output of your transmitter. This specific antenna handles up to 200 W CW.
• 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 changed for Espy's compact monitoring system? Cyntony helped Espy source antennas that fitted a compact transit case and coordinated later sourcing revisions for removable mounting. This documented result concerns Espy's system; it does not establish this product's dimensions, mounting features or performance (Espy case study).
