AD-25/C — Portable VHF Manpack Tape Antenna

Overview

The AD-25/C is a family of flexible, multilayered tape antennas designed for VHF band operation. Built for robust field use, these omnidirectional antennas provide reliable connectivity for portable and manpack radios equipped with integrated antenna tuners.

Technical Summary

• Frequency Range: 30 to 108 MHz
• Height Range: 760 to 1480 mm
• Standard Connector: M8 thread (custom threads available)
• Construction: Multilayered tape radiator with plastic sleeve

Operational Use Cases

Designed specifically for dismounted operators using portable and manpack radios in the 30 to 108 MHz band. The AD-25/C-GN variant features a goose-neck base, making it ideal for dynamic maneuvers where the operator must maintain a vertical antenna orientation regardless of how the radio is positioned.

Deployment Environments

Engineered for rugged dismounted operations, the multilayered tape radiator is protected by a durable plastic sleeve to withstand bending and physical stress during tactical field deployments.

Performance Metrics

• Operating Band: 30 to 108 MHz (VHF)
• Radiator Design: Flexible multilayered tape

Setup & Portability

The highly flexible tape construction allows the antenna to be easily collapsed when not deployed. Each antenna includes a velcro tape strap to ensure secure and compact storage during transport.

Compatibility

These antennas require connection to a portable or manpack radio equipped with an integrated antenna tuner. The standard physical interface is an M8 threaded connector, though custom thread options can be specified to match specific transceiver models.

FAQs

• What type of omnidirectional antenna is typically used for manpack radios? Manpack applications generally utilize monopole antennas, which rely on the radio chassis or the operator to serve as a counterpoise. Verify the radio's ground-plane requirements before selecting an antenna.
• Why is it important to keep an omnidirectional antenna vertical? A vertical orientation keeps the radiation pattern focused along the horizon, maximizing communication range. Tilting the antenna directs energy into the ground or sky, which degrades signal strength.
• What is AD-25/C — Portable VHF Manpack Tape Antenna used for? AD-25/C — Portable VHF Manpack Tape Antenna is categorized as Omni Antenna.
• 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).
