Product overview
The Kimpok KP-HDT1W provides a COFDM video transmission component for UAV integration. Its 167 × 90 × 25 mm enclosure and 515 g weight define the space and mass to accommodate within an installation. The transmitter supports H.264 video, a maximum specified resolution of 1920×1080P/I@ 60P, and balanced stereo audio input. Its built-in HD or HD-SDI interface is a single-selection configuration, so the input choice forms part of the equipment specification rather than providing two simultaneous HD inputs.
Integration requires a DC11V–DC16V supply, with working current specified as no more than 1.1 A at DC12.5V. RF output adjusts from 1–3 W in 1 dB steps, while bandwidth is selectable at 4 or 8 MHz. Transmission distance is specified separately for airborne line-of-sight operation at 1–40 km and ground-to-ground non-line-of-sight operation at 1–2 km. Operating temperature spans −25°C to 55°C. The encryption entries include AES128/256bits for the transmitter and a separate HD-interface entry of AES 128/265 bit or ALLTECH Basic scrambling.
