Product overview
The Kimpok Technology KP-HDT2W-1 is a UAV video transmitter built around COFDM modulation and H.264 video encoding. Its role is to carry camera video over a wireless link, with support for composite standard video and balanced audio as well as an HD input. The built-in HD connection is selected as either HDM-I or HD-SDI. That single-selection configuration matters when matching the transmitter to a camera or other video equipment: the two HD interfaces are alternatives.
The transmitter measures 167 × 90 × 25 mm and weighs 515 g, defining the physical space and mass required for installation. Electrical integration requires DC11V–DC16V, with working current of ≤1.1A at DC12.5V. RF output is adjustable from 1–2W in 1dB steps, with adjustable 4/8MHz bandwidth. Transmission distance is 20–60km for airborne line-of-sight operation and 1–3km for ground-to-ground non-line-of-sight operation. Operating temperature is limited to −25°C through 55°C, while storage spans −40°C through 70°C.
