Foxeer Reaper 3.3GHz 4W
Of the 13 other 3.1-4.0 GHz analog video transmitters in our database, 4 have a lower maximum power than the Reaper 3.3GHz 4W (4000 mW, 36 dBm), 4 the same and 5 a higher one; the class median is 4000 mW. The Reaper 3.3GHz 4W steps through 250 / 500 / 1000 / 2000 / 4000 mW, which is 24 / 27 / 30 / 33 / 36 dBm: the top level is 12 dB above the lowest, about 4.0x the free-space range on the same antennas.

saveSource: https://download.foxeer.com/FOXEER_Reaper_3.3G_4W_VTx_Frequency_Table.json — Foxeer's own Betaflight VTX config file (FOXEER_Reaper_3.3G_4W_VTx_Frequency_Table.json), linked from the product page's Downloads list. Five bands A-E of eight channels, 3170-3630 MHz, identical cell for cell to the page's own grid - this is a 3.3 GHz transmitter, so none of the band letters mean the 5.8 GHz band of the same name. The five power levels are the page's own Power line read across (250mW/500mW/1W/2W/4W). Foxeer pads the file's "name" and "label" fields with spaces to Betaflight's field width; they are stored here without the padding.
Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from
Foxeer's own spec table (SKU MR1847, 'Name: Reaper 3.3G 4W VTx'): 9~36V in, 5V out, Tramp control, 40CH, 250mW/500mW/1W/2W/4W, 29.8 g, 50*34*14.5 mm, 'Mounting Hole: 2 Groups/20*20mm M2 2.5mm depth' (two 20x20 groups, i.e. it bolts to a 20x20 stack either way round), fan, 2.1 A at 10 V. frequency_range is the span of the page's own channel table - five bands of eight from 3170 MHz (band E ch1) to 3630 MHz (band C ch8) - rather than the '3.3G' of the title, which is the class label. A 3.3 GHz link needs a licence in most countries; check local rules before transmitting. power_draw is the maker's own supply figure, 'Consumption: 2.1A/10V', read 2026-10-17; it is the VTX's input draw, not its RF output.
