RUSHFPV XSPAN 3.1-3.9GHz 10W
Of the 13 other 3.1-4.0 GHz analog video transmitters in our database, 12 have a lower maximum power than the XSPAN 3.1-3.9GHz 10W (10000 mW, 40 dBm) and 1 the same; the class median is 4000 mW. The XSPAN 3.1-3.9GHz 10W steps through 25 / 200 / 2000 / 10000 mW, which is 14 / 23 / 33 / 40 dBm: the top level is 26 dB above the lowest, about 20.0x the free-space range on the same antennas.

Where this data comes from
Board marking XN-31391. The module's own label prints the power steps (PIT / 25 / 200 mW / 2 W / 10 W), five bands A-E spanning 3170-3950 MHz, eight channels per band, and a 7-30 V dual DC-in. RushFPV's product page carries no spec block, so every figure here is read off that label. X-SPAN is RushFPV's name for its wideband analog module line - a standalone brick with an SMA jack, a fan and a dual DC-in that also feeds the camera, not a board you bolt into a stack. RushFPV publishes no weight and no mounting pattern for the class, so those columns stay empty. Output above the lowest step is licensed spectrum in most countries; the module's own label carries that reminder.
