Communications relay module
Vardiron Relay
Vardiron Relay is an interchangeable, self-contained communications module that extends FPV control and video transmission across obstructed terrain and limited line of sight.
Operates as an intermediate communications node — typically carried by Vardiron 15-R or integrated into the wider control architecture.
Detailed overview
Mission role
Use the relay when direct line of sight is blocked by terrain, urban structure or distance. Interchangeable TX, VRX and VTX modules adapt frequencies and standards without changing the core device architecture.
Power architecture
A carefully engineered circuit with a high-efficiency synchronous DC-DC converter and reinforced filtering provides clean power for sensitive video equipment, minimising ripple and interference.
Field sustainment
The interchangeable 55 Wh battery supports more than three hours of autonomous operation. Rapid battery replacement allows continued use without lengthy downtime or tethered external power.
Key capabilities
- Intermediate node for control + video under obstructed LOS
- Designed for use with airborne carriers such as Vardiron 15-R
- Professional power filtering for sensitive VTX/VRX chains
Engineering advantages
Modular RF configuration
Swap TX/VRX/VTX modules for required frequencies and communications standards.
Self-contained power
Interchangeable 55 Wh battery for more than 3 hours autonomy with rapid battery swaps.
Clean video power
Synchronous DC-DC and reinforced filtering for low-noise video transmission.
Orderable customs
Custom configurations available beyond the standard 5.8 / 3.3 / 4.2 matrices.
