AD-64/B — Ultra Wideband Manpack Antenna

Overview

The AD-64/B by Trival Antene is an ultra wideband manpack antenna designed for modern broadband software-defined radios (SDR). Featuring a center-fed sleeve dipole design, it operates efficiently without requiring a ground plane and includes a flexible gooseneck for rugged military use.

Technical Summary

• Frequency Range: 225 - 1000 MHz
• Maximum Power: 50 W CW
• Impedance: 50 ohms
• VSWR: < 3:1 typical
• Polarization: Linear Vertical
• Connector: N male

Operational Use Cases

Designed for tactical communication, the AD-64/B supports broadband SDR applications in harsh military environments. Its flexible gooseneck and ground-plane independence make it suitable for manpack deployments where versatile positioning is required.

Deployment Environments

The radiating element is fully enclosed in a rugged fiberglass radome built to protect against external elements. The durable construction is specifically intended to withstand the rigors of harsh military field environments.

Performance Metrics

This antenna provides continuous coverage across the upper VHF and lower UHF bands from 225 to 1000 MHz. It handles up to 50 W CW of maximum power and maintains a typical VSWR of under 3:1 with a 50-ohm impedance.

Setup & Portability

The inclusion of a flexible gooseneck allows the antenna to be bent into almost any position. The center-fed sleeve dipole design ensures efficient operation without the need to establish a ground plane on the mounting platform.

Compatibility

Intended for use with modern broadband software-defined radios (SDR). Connections are made via a standard N male connector.

FAQs

• What is the advantage of a sleeve dipole design for manpack antennas? Sleeve dipole antennas operate independently of a ground plane. This allows for efficient radiation without relying on the physical dimensions or conductivity of the mounting platform.
• How should the antenna be positioned to maintain linear vertical polarization? The antenna element must remain physically vertical to match vertically polarized signals. The integrated flexible gooseneck allows operators to keep the radome upright regardless of how the manpack is carried.
• How does gain vary across the wideband frequency range? Wideband antennas typically exhibit lower gain at the lowest operating frequencies. Verify the manufacturer's specific gain diagram to confirm performance meets system requirements across the 225 to 1000 MHz band.
• 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 did Cyntony's tactical-link field test establish? Cyntony's 2025 XTND-DIRECT field test showed how terrain, antenna height and clearance affected a specific mesh-radio link. The result informs deployment questions; it does not establish range, throughput or suitability for this product (Field-test account).
