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

Overview

The AD-25/CW-3512-TNC is a wideband VHF/UHF monopole antenna engineered for manpack radios operating between 30 and 512 MHz. It features a durable matching unit and a tape radiator designed for demanding tactical communication applications.

Technical Summary

• Frequency Range: 30 to 512 MHz
• Antenna Type: Monopole / Omnidirectional
• Power Handling: Up to 10 W CW
• VSWR: Less than 3.5
• Connector: TNC Male
• Weight: 410 g

Operational Use Cases

Intended primarily for manpack radios, this antenna supports tactical communications across the VHF and UHF bands. The wideband design allows operators to cover multiple frequency segments with a single continuous-coverage aerial.

Deployment Environments

Built for rugged field environments, the antenna features a passive transformer enclosed in a hard plastic housing. All metal components within the matching unit are galvanically protected to withstand harsh conditions.

Performance Metrics

• Maximum Continuous Power: 10 W CW
• VSWR: < 3.5

Setup & Portability

Weighing just 410 grams, the antenna adds minimal burden to dismounted operations. A flexible gooseneck positioned between the tape radiator and the matching unit allows operators to maintain optimal vertical orientation during movement.

Compatibility

This antenna integrates with tactical manpack transceivers operating within the 30 to 512 MHz frequency range. It attaches to equipment using a standard TNC connector.

FAQs

• Why are monopole antennas commonly used for manpack radios? Monopoles are frequently selected for handheld and manpack platforms because the radio chassis and operator can act as a necessary counterpoise. Portable or fixed-site applications typically require dipoles instead.
• What is the typical radiation pattern of an omnidirectional monopole? An omnidirectional monopole typically exhibits peak gain near the horizon with nulls located directly above and below the antenna. Verify the manufacturer's measured elevation pattern to confirm angular coverage.
• How does transmit power affect antenna selection? The antenna must safely handle the maximum continuous output power of the transmitter while maintaining an acceptable VSWR. Verify that the radio's reflected power limits align with the antenna datasheet.
• 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).
