HDZero Eco VTX

Of the 10 other 5.8 GHz HDZero video transmitters in our database, none has a lower maximum power than the Eco VTX (200 mW, 23 dBm), 7 the same and 3 a higher one; the class median is 200 mW. The Eco VTX steps through 25 / 200 mW, which is 14 / 23 dBm: the top level is 9 dB above the lowest, about 2.8x the free-space range on the same antennas.

Where this data comes from

HDZero's own product page prints the labelled block: Model HDZero Eco VTX, SKU HDZ3160, Frequency 5.8G, Resolution Default 1280*720@60fps, RF power 25mw/200mw, RF Connector U.FL, Interface Composite HD, Size 32.4x32.5mm (29x29mm inner), Weight 4.5grames/4mm Thickness (w/o shielding), Power 1000mA@5V, power input 1S-3S, Mounting 25.5x25.2 M2 soft mounting. The one VTX in the HDZero line that takes composite HD video over a single wire instead of a MIPI cable, which is why it pairs with the LUX/Eco camera and not with the MIPI cameras the rest of the system uses. mount_mm and input_voltage are the HDZero VTX User Manual v1.1 figures (p2 product table: 25.5x25.5, M2 (Soft), 4.5grams, 4V-12V, 5~6W, RF power output 25mW/200mW), because three manufacturer statements of the mounting pattern disagree in the last digit - 25.5x25.2 on the product page, '25 x 25 M2 Soft Mounting' on the Eco Bundle page and 25.5x25.5 in the manual - and 25.5x25.5 is the only one of the three that is a pattern frames are sold for. The manual's own Dimension row for this model (29x30) is not used: it repeats the Freestyle V2's figure and contradicts the product page's 32.4x32.5mm. channels is the manual's 'All VTXes support R1-R8, E1, F1, F2 and F4 channels' (p8), twelve; eight more (L1-L8) appear only after the low-band unlock firmware is flashed. power_draw is the maker's own supply figure, 'Power Consumption: 5~6W' in the ECO column, read 2026-10-17; it is the VTX's input draw, not its RF output. The 12 channels are, by the HDZero VTX User Manual v1.1's menu page (p8, re-read 2026-10-20), R1-R8, E1, F1, F2 and F4, with L1-L8 added only by the regional low-band unlock (p18). The manual names channels, not frequencies, and the product page's 'Frequency 5.8G' is the only frequency figure, so frequency_range keeps that label.
