FAQ About FPV VTX & Wireless Video Transmitters

What frequency range does this 3.6-4.2G analog VTX use? What advantages compared with 5.8G VTX?

This video transmitter works on 3.6GHz–4.2GHz. Compared with 5.8GHz, it has longer wavelength and better diffraction performance. It works more reliably under trees, hills and partial obstacles. Analog video has no encoding delay, and the signal will turn snowy gradually instead of blackout suddenly when signal weakens, ideal for long range FPV and industrial inspection drones.

What is the maximum transmission range?

In open line-of-sight, clean RF environment with matched high-gain antenna, it can reach several 8-12km. Actual range depends on transmit power, antenna gain, SWR, obstacles, local interference and local radio power regulations. Range will drop heavily in dense forest or urban areas. such as forests and buildings.

Will it interfere with 2.4G remote control or 5.8G devices?

The 3.6-4.2GHz band is isolated from 2.4G RC and standard 5.8G VTX, so cross-interference is low normally. If multiple 3.6-4.2G transmitters work at the same site, you need to set different channels to avoid crosstalk.

What UAV application scenarios suit this 3.6-4.2GHz high power VTX?

Widely applied in power line inspection, forest survey, mountain reconnaissance, urban emergency monitoring, fixed-wing long-range cruise and multi-rotor industrial drone projects. It perfectly solves frequent signal loss issues of 5.8GHz transmitters in obstructed environments that demand long-distance anti-block video links.

How stable is the 10W VTX under long-duration high-power operation?

Equipped with professional RF power amplifier and high-efficiency cooling system including built-in cooling fan and full-coverage heat sink. It maintains steady 10W full-power output without power drop or thermal throttling during continuous long-time flight for outdoor industrial missions.
