Series STM — Lightweight Manportable Sectionalized Tubular Mast

Overview

The Series STM is a family of lightweight, manportable sectionalized tubular masts designed for the rapid deployment of lightweight antennas. Featuring composite fiberglass sections and durable aluminium joints, these masts offer scalable heights from 3 meters to 8 meters to support tactical communications in the field.

Technical Summary

• Construction: Composite fiberglass sections with aluminium joints
• Finish: 2-component UV resistant PU paint
• Erected Heights: 3m to 8m (options available upon request)
• Payload Capacity: 4 kg to 8 kg maximum top load

Operational Use Cases

• Tactical Communication
• Rapid temporary antenna elevation
• Manpack and dismounted operations

Deployment Environments

Designed for field deployment in tactical environments. The system includes ground mounting accessories to facilitate setup in varied outdoor terrain.

Performance Metrics

• Top Load Limit: 4 kg to 8 kg (depending on specific model configuration)
• Height Availability: 3m, 5m, 7m, and 8m variants

Setup & Portability

• Erection Time: Approximately 5 minutes
• Personnel Required: 1 to 2 operators
• Portability: Sections and accessories pack into an included strong canvas carrying bag

Compatibility

Intended for use with lightweight antennas. Customization options for section length, number of sections, guy levels, and guy counts are available upon request to match specific payload requirements.

FAQs

• What factors determine the required guying configuration for a sectioned mast? Guying requirements depend on the final erected height, wind conditions, and the size of the mounted antenna. Verify the manufacturer's specific guying levels and ground anchor recommendations for the chosen mast height.
• How do sectionalized tubular masts ensure stability? Sectionalized structures rely on joined rigid tubes, typically constructed from lightweight composites. Stability is achieved by securing the assembled structure with tensioned guy ropes anchored to the surrounding ground.
• What is the standard procedure for erecting a manpack mast? Erection generally involves assembling the tubular sections, attaching the payload, and raising the mast while securing guy lines. Operators should confirm specific assembly instructions and anchor placements with the provided manual.
• Problems we solve: how do we choose a mounting or mast solution? Antenna loads, available space and deployment conditions can make mounting selection difficult. Bring those constraints to Cyntony to narrow options and identify load ratings, installation details and manufacturer questions that need 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).

Video Notes
