AD-25/CW-3512 — Manpack VHF/UHF Wideband Whip Antenna

Overview

The AD-25/CW-3512 is a wideband monopole whip antenna engineered for manpack radios operating across the 30 to 512 MHz VHF and UHF frequency bands. It features a rugged, bendable tape radiator and an integrated goose-neck, allowing for optimal vertical positioning regardless of the radio's orientation.

Technical Summary

• Frequency Range: 30 to 512 MHz (VHF/UHF)
• Antenna Type: Wideband Monopole Whip / Omni Antenna
• Design Features: Bendable tape radiator with integrated goose-neck
• Connector Options: TNC, N-type, or SINCGARS compatible threads
• Ground Plane: Optimized for small ground planes

Operational Use Cases

Optimized for tactical communications, this antenna is primarily utilized with manportable radio units and other RF devices featuring small ground planes. Its flexible construction is designed to withstand the physical demands of dismounted field operations.

Deployment Environments

The antenna is built for rugged tactical environments. The bendable tape radiator provides high flexibility to resist damage from impacts or snags, while the included velcro strap ensures secure and compact stowage when not actively deployed.

Performance Metrics

The standard model provides wideband coverage from 30 to 512 MHz and features a matching unit located directly above the connector. A high-power variant (AD-25/CW-3512-HP) is also available, extending the lower frequency limit down to 25 MHz and increasing power handling capabilities up to 50W.

Setup & Portability

An integrated goose-neck enables the antenna to remain vertically oriented even when the operator is moving or the radio shifts position. A velcro strap is included to securely fold and stow the tape radiator during transport.

Compatibility

The antenna is compatible with a wide range of manpack radios and is available with multiple connector options, including TNC, N-type, and SINCGARS compatible threads.

FAQs

• Why are monopole antennas well-suited for manpack radios? Monopole antennas rely on the radio chassis to serve as a counterpoise or ground plane. This design provides effective RF radiation while keeping the physical antenna structure compact for tactical environments.
• Why is vertical positioning important for omnidirectional whip antennas? Maintaining a vertical orientation aligns the radiation pattern with the horizon to optimize the signal path. If the antenna tilts, the elevation pattern shifts, which can direct energy away from intended receivers.
• How should the antenna connector be selected for deployment? Verify the specific RF interface on the intended transceiver. This antenna is available with multiple options, including TNC, N-type, and SINCGARS-compatible threads, to match various radio units.
• 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).
