Product overview
The DMKR 3.3G 4W 16CH FPV Analog VTX is a standalone analog video transmitter module, not a complete aircraft or an airframe kit. It is built for long-range UAV video transmission, with an emphasis on high RF output, stable operation and flexible integration. The module covers 3170–3470MHz across 16 selectable channels. Output power can be set to 25mW, 2W or 4W, so the same unit can handle low-power testing as well as high-power transmission. The design also supports customization and system-level integration for OEM and ODM projects across different UAV platforms.
The module measures 53×28.85×16mm, weighs 25.85g and mounts on a 20×20mm hole pattern, and the antenna attaches through an SMA connector. It accepts 7–36V DC and works with 2–8S battery systems, so it can be integrated without extra voltage regulation. Power, video and control signals all run through a standard 6P interface. With IRC-Tramp support, frequency and power can be adjusted remotely through the flight controller or OSD interface. Handling requirements: install the antenna before powering on, provide enough cooling during high-power operation, check the input voltage before connecting, and avoid wiring mistakes, which can damage the module.
