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.

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.Applications
