Skyzone VT1225 1.2G 2.5W VTX
Of the 10 other 1.2/1.3 GHz analog video transmitters in our database, 6 have a lower maximum power than the VT1225 1.2G 2.5W VTX (2500 mW, 34 dBm) and 4 a higher one; the class median is 2000 mW. The VT1225 1.2G 2.5W VTX steps through 25 / 800 / 1600 / 2500 mW, which is 14 / 29 / 32 / 34 dBm: the top level is 20 dB above the lowest, about 10.0x the free-space range on the same antennas.
Skyzone's own Betaflight VTX table is on this page: 2 bands of 8 channels, 960–1400 MHz, 4 power levels. CLI commands and JSON file.

The product page prints no grid and no power ladder (it states 2.5 W), and neither names the control protocol; the values are the file's, not milliwatts.
Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from
Read 2026-09-25 off the brand's own shop, the fifteenth VTX manufacturer catalogue read beside the US retail scrape. www.skyzonefpv.com and atomrc.com are two Shopify stores of one company: /products.json?limit=250 is the whole catalogue in one request on each, the two shops carry the same product_type taxonomy and each lists the other brand's transmitters, and the boards are silkscreened with the brand whose name is on the case rather than the one in the page title. The page is its title and one sentence - 'SKYZONE VT1225 1.2G 2.5W VTX With CNC Case and Fan' - and its images are renders. max_power_mw is the 2.5W the brand names the part with, on both of its shops. The channel count and the band edges come from the brand's own Betaflight VTX table for this model, linked from /pages/download as 'VT1225 VTX table': two bands of eight, SKYZONEA 1080/1120/1160/1200/1240/1280/1320/1360 MHz and SKYZONEB 960/980/1000/1020/1040/1258/1380/1400 MHz. That file's power labels ('25 ', '800', 'HIG', 'MAX') are Betaflight's three-character display strings, not figures,. Re-read 2026-10-20 (burst 227): the product page's description now carries one spec sheet, VT1225_1.jpg (1000x2000, read at full resolution), headed 'VT1225 CNC VTX'. Its frequency table prints the same two bands of eight as the Betaflight file, cell for cell, and its rows give Power '25mW、800mW、1600mW、2500mW' (power_levels_mw), Antenna port 'mmcx', Input voltage '9~26V', mounting '30.5*30.5*M3', size '38.8*38.6*21mm' and weight '27.5g'. The 9-26V rail, 30.5 mounting and 27.5 g are also what Skyzone's TX2501 CNC sheet prints for that case; this sheet carries the VT1225's own 1.2 GHz table, so it is this model's sheet and not a copy of the 5.8 GHz one.
