Skyzone TX2501
Of the 81 other 5.8 GHz analog video transmitters in our database, 61 have a lower maximum power than the TX2501 (2500 mW, 34 dBm), 10 the same and 10 a higher one; the class median is 800 mW. The TX2501 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.

saveSource: https://cdn.shopifycdn.net/s/files/1/0597/9668/4956/files/TX2501_240111.pdf — Grid from the TX2501 manual's Frequency Table (TX2501_240111.pdf, one page); band names as the maker's own Betaflight file prints them (https://cdn.shopify.com/s/files/1/0597/9668/4956/files/TX2500_TX2501_vtx_table_25mw_2500mw_ch_ABEFRLX_230601.json, linked from the TX2501 page). The file and the manual agree on 55 of 56 cells: the file prints B5 as 5999 inside a ladder reading 5790, 5809, 5828, the manual 5809. Power: the manual, the product page and the file's own name state 25/800/1600/2500 mW; the file labels its four levels 025 / 1.2 / 2.0 / 2.5 with values 1-4. The manual calls the control IRC (Tramp), where Betaflight sends milliwatts, so the values stored are the manual's mW figures. The manual also prints an X-band output curve (1 W at 4990 MHz rising to 2.5 W at 5200 MHz) that no table slot carries.

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. This is the heat-sink TX2501, the version without the CNC case and fan; its board is silkscreened 'TX2501 231115 V1.0'. The page's feature list says '800/1600/2500mW adjustable power output' and 7-26V input; the brand's own one-page user manual, linked from the same page, says '25/800/1600/2500mW adjustable power output' over the same 7-26V and prints the frequency table this field holds: 7 bands (A B E F R L X) of 8 channels, 4990-5945 MHz, with X band running 4990-5200 MHz. The manual is the document that enumerates the steps, so power_levels_mw takes its four; both agree on the 2500 mW maximum. The page also links a Betaflight VTX-table JSON the brand named TX2500_TX2501_...: its band and channel list matches the manual except for one entry - band B CH5 reads 5999 MHz where the manual prints 5809 - so the config file's span is a typo and the manual's is what is recorded here. Its power labels ('025', '1.2', '2.0', '2.5') are Betaflight's three-character display strings and not a spec. One of the page's four images is a spectrum-analyser capture (Agilent, 'C:\TX2501.STA file loaded') reading 3.229 W at 5.918 GHz; that is a measurement of one unit at one channel, not a rated figure, and nothing was taken from it. The brand states no weight, mounting pattern or antenna connector for this version.
