Caddx Walksnail Ascent Lite Kit
Of the 4 other 5.8 GHz Walksnail video transmitters in our database that state an output power, none has a lower maximum power than the Walksnail Ascent Lite Kit (100 mW, 20 dBm) and 4 a higher one; the class median is 500 mW. The Walksnail Ascent Lite Kit steps through 25 / 100 mW, which is 14 / 20 dBm: the top level is 6 dB above the lowest, about 2.0x the free-space range on the same antennas.

Where this data comes from
Walksnail's own product page states the output levels in milliwatts in the feature copy - 'switches between 25mW and 100mW output' - and prints no EIRP row at all, so there is nothing for this figure to contradict. Output power, the same quantity as the analog listings in this column. The retail listing is a second source for the power figure and agrees: it prints 'Transmit Power (EIRP): <20dBm', and 20 dBm is 100 mW - an EIRP ceiling that matches the manufacturer's stated 100 mW output rather than exceeding it. mount_mm is that listing's 'Mounting Hole: 25mm' line, read as the 25x25mm square those holes describe. It used to hold '14x15mm', which is two of the three figures in 'Camera: 12 x 14 x 15mm' - the camera's body, not the transmitter's holes. Confirmed 2026-09-23 against Walksnail's documentation wiki, which states the range rather than the top step: 'With selectable transmission power from 25 to 100 mW'. The product page's spec block confirms the rest - name 'Ascent Lite VTX', model WN13-4S09B, 5.730-5.815 GHz, 'Mounting Hole 25mm', '6g (Antenna not included)', 3 channels, 3V~12.6V in, one IPEX-1 antenna, VTX 30.5*30.5*3.5mm. Weight withheld 2026-10-20 (223rd burst): the owner's ruling of 2026-10-20 makes a VTX kit's weight_g the camera-excluded figure, and this kit ships its camera ('1x Ascent Lite Kit (Camera Included)'), and its one '6g (Antenna not included)' sits beside 'Camera:12 x 14 x 15mm' and 'VTX: 30.5 x 30.5 x 3.5mm'. Nothing the maker prints says whether the camera is in that figure, so weight_g stays empty until it does.
