DarwinFPV Cement 5.8G 1000mW VTX
Of the 81 other 5.8 GHz analog video transmitters in our database, 44 have a lower maximum power than the Cement 5.8G 1000mW VTX (1000 mW, 30 dBm), 6 the same and 31 a higher one; the class median is 800 mW. The Cement 5.8G 1000mW VTX steps through 200 / 800 / 1000 mW, which is 23 / 29 / 30 dBm: the top level is 7 dB above the lowest, about 2.2x the free-space range on the same antennas.

Where this data comes from
Read 2026-09-24 off DarwinFPV's own shop. This is the fullest spec block the brand publishes for any transmitter and every field here is one of its labelled lines: 'Output power : 200mW/800mW/1W', 'Input Voltage : DC7-24V(2-6S)', 'Frequency range : 5645-5945MHz (5.645-5.945GHz)', 'Frequency group : 40 channel(A/B/E/F/R frequency group)', 'Antenna interface : MMCX', 'Mounting Hole Size : 30.5mm x 30.5mm(M3)', 'Weight : 9.2g+-5g (without antenna and power cable)', 'Size : 38mm x 37mm x 4.5mm'. The weight tolerance is printed as +-5g on a 9.2 g part, which cannot be what the brand means and is recorded here as the 9.2 figure alone. Also stated: rated current 10V/600mA at 1000mW/30dBm, input impedance 75 ohm, SmartAudio, OSD parameter adjustment, IP67, NTSC/PAL, operating range -10C to 50C, no microphone. The 30dBm in the current row is the 1000 mW restated, not a separate EIRP claim, so max_power_mw takes the brand's own milliwatt figure. price_usd is the plain SKU; the same page sells a 'Care Card' bundle at $44.99, which is a warranty product and not this radio. power_draw is the maker's own supply figure, 'Rated current(Tested at maximum power) : 10V/600mA@1000mW/30dBm' in the Specifications block of DarwinFPV's product page, read 2026-10-20 through scraper/propose_vtx_power_draw.py (the store's products.json, common.UA); it is the VTX's input draw, not its RF output.
