EMAX F4 Magnum II VTX
Of the 81 other 5.8 GHz analog video transmitters in our database, 3 have a lower maximum power than the F4 Magnum II VTX (200 mW, 23 dBm), 4 the same and 74 a higher one; the class median is 800 mW. The F4 Magnum II VTX steps through 25 / 200 mW, which is 14 / 23 dBm: the top level is 9 dB above the lowest, about 2.8x the free-space range on the same antennas.

Where this data comes from
EMAX's own labelled block, printed above the marketing copy on its store page: 'Replacement part for Buzz Freestyle quadcopter. Frequency band: 5362-5945MHz. Audio Control. Channels: 37. Transmit power: 14dBm/23dBm (25mW/200mW). Supply voltage: 4.5V-5.5V. Antenna port: 50 Ohm.' The power steps are stated twice in one line and the two statements agree with each other: 14 dBm is 25.1 mW and 23 dBm is 199.5 mW, so the milliwatt figures are the conducted output the dBm figures convert to, not an EIRP ceiling a brand has restated in round numbers. frequency_range is that stated 5362-5945 MHz band, written as GHz the way this column already holds measured spans. The factory VTX of the EMAX BUZZ, sold as an OEM replacement board. antenna_connector is empty: the block states the port's impedance (50 Ohm) and not its type. No weight or mounting pattern is stated.
