Where this data comes from
max_power_mw and power_levels_mw from DJI's O4 Air Unit Series user manual v1.0 (section 4.3, p17): 'DJI O4 Air Unit Pro: The maximum available transmission power levels are 25mW, 50mW, 100mW, 200mW, 400mW, 700mW, and 1200mW.' The same page adds that above 700mW the unit trims itself between the set value and 700mW based on the flight environment, so 1200 mW is the ceiling, not a sustained figure. Output power in milliwatts, not EIRP. Two scraped fields were cleared rather than published: mount_mm held '33.5x13mm', which is two of the three figures RaceDayQuads prints as 'Dimensions: 33.5 x 33.5 x 13 mm (L x W x H)' on the matching module SKU, and weight_g held 2.1 g on a kit whose camera-less transmission module the same retailer weighs at 15.6 g. Neither is replaced here, because DJI's manual states the mounting holes only in a drawing and carries no weight table.
