RUSHFPV XSPAN 3.1-3.8GHz 5W
Of the 13 other 3.1-4.0 GHz analog video transmitters in our database, 9 have a lower maximum power than the XSPAN 3.1-3.8GHz 5W (5000 mW, 37 dBm), 2 the same and 2 a higher one; the class median is 4000 mW. The XSPAN 3.1-3.8GHz 5W steps through 25 / 200 / 1000 / 5000 mW, which is 14 / 23 / 30 / 37 dBm: the top level is 23 dB above the lowest, about 14.1x the free-space range on the same antennas.

Where this data comes from
Board marking 31385. Label: power steps PIT / 25 / 200 mW / 1 W / 5 W, four bands printed as MHz spans (3330-3470, 3170-3310, 3490-3630, 3650-3790), eight channels per band, 7-30 V Lipo-in. The 3.17-3.79 GHz range is those four spans end to end; the model is sold as '3.1G-3.8G'. 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.
