Product overview
The DMKR 1.2G 4W 9CH FPV Analog VTX is a standalone video transmitter module, not a flight platform or an airframe. It is built for long-range UAV video transmission, where a stable link matters more than small size or low power draw. The module works in the 1.2GHz band and offers nine channels. Output power can be set to pit mode, 25mW, 2000mW or 4000mW. This lets one unit be set up for short-range testing or for long-range flight missions, depending on system requirements. The design focuses on high RF output, system stability and flexible integration, and the module is offered for OEM and ODM customization across different UAV platforms.
The transmitter has an aluminum shell measuring 53×28.85×16mm and weighs 25.85g. It mounts on a 20×20mm hole pattern and uses an SMA antenna connector. It accepts 7–36V DC, so it can connect directly to 2–8S LiPo packs without additional voltage conversion. IRC-Tramp support lets operators change settings remotely through a flight controller or OSD system. Some operating limits apply. Install the antenna before applying power, and provide enough cooling when running at high power. Check the input voltage before connecting the module, and wire it correctly, because improper wiring can damage it.
