Ultra 1600 5.8 GHZ 1.6W Adjustable VTX

Ultra 1600 5.8GHz VTX – High-Power Adjustable Long-Range Transmission Module

The Ultra 1600 5.8GHz VTX is engineered for pilots who require strong and stable analog video transmission across extended flight distances. Designed with a maximum output of 1600mW (1.6W), this transmitter delivers reliable signal penetration for long-range FPV missions while maintaining multi-level power flexibility for racing and freestyle environments.

Ultra 1600 5.8GHz VTX Adjustable Power Levels

This module supports six selectable output levels: 25mW, 200mW, 400mW, 800mW, 1600mW, and Pit Mode. Lower power levels are ideal for racing tracks or crowded RF environments, while 1600mW mode enhances signal strength during long-range flights. The integrated temperature protection system actively regulates heat output to prevent thermal damage during sustained high-power operation.

Ultra 1600 5.8GHz VTX Wide Voltage Input & 5V BEC Output

Supporting a broad DC input range from 7V to 36V (2–8S LiPo), this VTX integrates smoothly into diverse drone builds without requiring additional voltage regulators. It also provides a 5V @ 600mA output to power an FPV camera directly, simplifying wiring and reducing overall system complexity.

Stable Signal Transmission with 64 Channels

The transmitter operates across 4.9GHz to 5.8GHz frequency bands with 64 selectable channels. Multiple regional frequency tables allow compatibility with international flight regulations. Input impedance is optimized at 75Ω to maintain analog signal integrity and minimize interference.

Smart Control via IRC Tramp Protocol

Built-in IRC Tramp protocol support enables direct power and channel adjustments through flight controller OSD. This eliminates the need for manual button configuration after installation. The board includes one functional button and three LED indicators for quick status verification during setup.

Cooling & Interference Shielding Design

A two-layer PCB structure separates the BEC section from the main transmission board. This design reduces internal signal interference and enhances electrical stability. The aluminum heatsink improves heat dissipation during prolonged high-power operation, making it suitable for endurance-based missions.

Built-In Microphone for Real-Time Audio

The integrated microphone captures ambient drone audio and transmits it in real time alongside the video feed. This feature enhances situational awareness for long-range pilots and inspection operations.
