Where this data comes from
Happymodel's product post prints the block: Brand name: happymodel, Item name: whoop_VTX_hp, Output power: 25~400mw switchable, Frequency: 40CH, Input voltage: 5V, Current consumption: 400mA(type), Antenna: directional linear U.FL interface, Frequency: 5.8GHz 5bands 40 channels, With Raceband, Smartaudio ready, Weight: 2.8g with antenna. weight_g is deliberately empty: the only weight the page states includes the antenna, and every other weight in this column is the module without one. The 'Package included' line on the same page reads '1x happymodel whoop_VTX_hp 5.8G 40CH 25mW~200mW Switchable VTX' - the non-HP board's figure copied into the HP's packing list; the post title, the spec block and the discontinuation notice all say 25~400 mW, so the packing list is the error. power_levels_mw is empty because the page states a range and no steps. Discontinued, with the OVX306 named as the replacement; this is the transmitter the Cine8 kit shipped with before 25 Feb 2022. power_draw is the maker's own supply figure, 'Current consumption: 400mA(type)', read 2026-10-17; it is the VTX's input draw, not its RF output.
