Product overview
The Xingkai XK-F202THS is a compact wireless HD video transmitter intended for integration with equipment including UAVs and robots. Its transmission architecture combines COFDM modulation, H.265 video compression and AES encryption. The manufacturer describes applications involving rapid movement and obstruction by urban buildings, alongside non-line-of-sight transmission.
For installation planning, the published transmitter envelope is 108 × 85 × 27mm with weight no greater than 272g; a controller is separately specified at no greater than 70 × 72 × 13mm and 84g. Confirm these values against the selected configuration. HDMI and SDI video inputs, RS232 configuration and data ports, and a standard DC12V input define the principal integration interfaces. Transmitter hardware rather than a complete flight platform or airframe kit.
Procurement should retain the qualifications attached to the link figures: approximately 12km is published at 30dBm (1W), while 120–260ms end-to-end latency is specified with the XK-F200R receiver. Power consumption is likewise bounded at that RF output. The transmit-frequency entry requires clarification because its published range mixes MHz and Hz, although customization and 1MHz steps are stated. Receiver selection, frequency configuration and package contents therefore need confirmation before these published specifications can define an installation.
