Product Description

Miniature 1000mW lightweight line of sight 10km COFDM two wday video downlink


ST11HPT is a mini HD Video and Data transmission COFDM system for UAV. It develops CABAC (h.264) coding&decoding technology to achieve Utra-high resolution(1080P), long distance(air to ground 10km) and low delay(12-25ms) transmission. The system supports two-way(data&image) communication, adjustable video resolution, bit rate output with the TPlayer software. It can realize the soft decoding with low delay. Meanwhile this SUNTOR series products have small size, light-weight, low consumption, high stability and high sensitivity. They are suitable various environment of different application.



  • Ultra-high Resolution Image: Independently developed CABAC (h.264 + h.265) coding&decoding technology
  • Ultra-distance: Air to ground 10km
  • Ultra-low Delay: 12-25ms
  • Transmission Mode: PTP, PTMP for LOS and NLOS distance
  • Transmission Signal: Video, Audio and data(RS232)



  • High Definition Multimedia Interface input/output and support SBUS,PPM,TTL
  • Image & data transmission, combined multiple radio links into one radio link to transmit and receive
  • 1080p 60fps &30fps / 720P 60fps resolution adjustable
  • TPlayer for ultra low delay decoding, the delay 12-25ms
  • Support 100Mbps Ethernet to output



  • Support the 2.4GHz(2.402 - 2.478 GHz) TDMA OFDM
  • Support point to point, point to multipoint.
  • Radio communication mode: reconnection time < 1 ms.
  • Encryption: Communication Channel Encryption
  • Antenna: Omnidirectional antenna can increase the sensitivity of signal reception


As its miniature volume, precision design, lightweight and easy to carry, suitable used in long range air high speed wireless video data transmission purposes. Such as UAV, rotorcraft, micro UAV, drone, UGV, unmanned powered parachute and more video data transmission.
