Axisflying S-MURFS MINI VTX
Of the 81 other 5.8 GHz analog video transmitters in our database, 2 have a lower maximum power than the S-MURFS MINI VTX (100 mW, 20 dBm) and 79 a higher one; the class median is 800 mW. The S-MURFS MINI VTX steps through 25 / 50 / 100 mW, which is 14 / 17 / 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
Read 2026-09-24 off Axisflying's own site, the fourteenth VTX manufacturer catalogue read beside the US retail scrape and the third brand this catalogue carried no transmitter of at all. www.axisflying.com is a UEEShop store with no products.json; its sitemap is named after the domain and is linked only from robots.txt. Its whole transmitter line is /collections/vtx. The brand's own Download Center (/download/vtx) serves six VTX manuals through a public POST (do_action=action.getDownloadCheck), all one-page image-only PDFs rendered here at 6x with Quartz/CoreGraphics. This product page has no description text at all - every figure came off the brand's own description images, read at full resolution. Its Product Specifications panel states Model Smurfs Mini, Frequency Band 5.8G Band / 5 Groups / 40 Channels, Power Levels 25/50/100mW, Antenna Connector IPEX, Input Voltage 5-25V, Configuration Mode Button / OSD, Product Dimensions 30X30mm, Product Weight 3.1g, Mounting Hole Spacing 25.5X25.5mm, VTX Protocol IRC Tramp, Pit Mode Not Supported. Two further panels corroborate it: a photograph of the board on a 0.1g pocket scale reading 3.1, and a dimension drawing annotating 25.5mm and 30mm. The bare PCB is silkscreened 'VTX_100mW' and carries the AXIS FLYING logo. Note that this is the one board in the line whose mounting pattern is not 20x20mm and whose antenna port is not MMCX or SMA. Axisflying's own Product Specifications image prints 'Antenna Connector: IPEX' with no generation. IPEX-1 is the same connector as U.FL and is what the board carries - one micro-coax jack beside the 5.8G copper-tube whip the brand's Package Contents image shows terminated in it - so the column holds U.FL and this note holds the brand's unqualified word. Re-read 2026-10-20 (burst 211), description images 01-07: the spec table says '5.8G Band / 5 Groups / 40 Channels' and the Betaflight VTX-table screenshot holds A/B/E/F/R x 8 (5645-5945 MHz), but the User Guide's group setting reads 'L blinks 6 times. Cycles through A->B->E->F->R->L->A' - a sixth (LowRace) band the table omits. The maker's documents disagree on what the radio tunes, so frequency_range keeps the 5.8 GHz label.
