Source: https://ft.systems/wp-content/uploads/2026/08/VTX-4-8-7-2-CLI-1.zip — Copied from Betaflight_CLI_LOW.txt in the maker's settings download (https://ft.systems/wp-content/uploads/2026/08/VTX-4-8-7-2-CLI-1.zip), linked from https://ft.systems/en/video-transmitter-vtx-ft-4-8-7-2/ as 'Settings File'. The 176 channels are 22 bands BAND_A..BAND_V and Betaflight holds 8, so FT ships three files: LOW (this one, the eight bands under 6 GHz - Q, O, R, P, N, S, K, I), MID (J, L, M, T, U, V, A) and HIGH (B, C, D, E, F, G, H). Every cell here matches the frequency table on page 4 of the maker's manual FT_VTX_4.8_7.2_GHZ.pdf. The power values are the manual's own command figures: its lowest step reads 0 mW on the module's LED but is commanded as 9 mW, which is why the file labels it PIT - Betaflight's own Pit Mode is a separate function. Not published from the other two files: the manual prints BAND_D CH8 as 6570, a repeat of BAND_C CH8 inside a 20 MHz ladder the CLI file reads as 6730.. Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from

Ukrainian-made wideband transmitter: 176 channels in 22 bands (BAND_A to BAND_V) over 4867-7210 MHz, 52.25x28.85x19.2 mm, an aluminium heatsink with a fan, controlled over IRC Tramp. FT Systems quotes measured RF output of 2320-5490 mW across the range rather than one figure, because a wideband amplifier does not deliver the same power at every frequency - the 4000 mW here is the nominal setting, as on the 5.8 GHz sibling; at the 25 mW step the maker states up to 5 mW on 5.8 GHz and up to 100 mW in the 7.2 GHz band. The lowest step reads 0 mW on the module but the manual commands it as 9 mW. No weight: the product page says 30 g and the manual 25.85 g, which is the figure FT's 4.9-6 GHz manual prints for the thinner (16 mm) 5.8 model, so the two maker sources disagree one against one. FT prints the connector as 'SMA female'; the column holds one spelling per connector.
