5.8 GHz Analog VTX

ZYRO Air Analog

5.8GHz 2.5W Analog Video Transmitter

ZYRO Air Analog is a lightweight, high-power analog VTX module for FPV, lightweight aircraft, and latency-sensitive video links. It uses a high-strength CNC aluminum housing and a built-in micro turbo fan to balance heat dissipation, transmission stability, and installation convenience at high output power levels.

Adjustable Power Levels

Supports PIT, 25 mW, 400 mW, 800 mW, and 2500 mW operating modes for flexible range/compliance requirements.

Wide Voltage Input

Supports 7–36 V DC input for 2S–6S LiPo power systems — compatible with most airborne power configurations.

Active Cooling & Thermal Protection

Built-in micro turbo fan with automatic step-down above 100°C and restoration at 95°C for safe sustained operation.

OSD Serial Tuning

Compatible with IRC Tramp / TRAMP protocol for remote setup and power adjustment through flight controller OSD.

Complete Interface Set

Supports video input, audio input, dual 5 V outputs, GND, IRC, and DC input for comprehensive integration.

Lightweight Structure

Compact 38.7 × 26 × 11 mm form factor at only 15.6 g with CNC aluminum case for premium build quality.

Operation

Operation Guide

Parameter	Description
Band / channel button	Short press to change channel; hold 3 seconds to switch frequency band
Power button	Short press to cycle through PIT, 25 mW, 400 mW, 800 mW, and 2500 mW
Power indication	25 mW flashes once; 2500 mW flashes four times; hold 3 seconds to enter PIT mode
High-power operation	Always connect a matching antenna before using 400 mW / 800 mW / 2500 mW modes
OSD remote setup	Connect to flight controller TX, configure remotely from OSD menu using TRAMP protocol

Installation Notes

▸Install the antenna before powering on the device.

▸Set the transmitter and receiver to the same frequency.

▸The aluminum case may become hot during operation; avoid direct contact with high-temperature surfaces.

▸Do not exceed the 7–36 V input range.

▸The dual 5 V outputs are intended only for peripheral power supply and must not be back-fed.

▸If the outer case is removed to reduce weight, thermal performance may decrease at high power.
