ALIENTECH DUO 3 antenna signal booster range extender for DJI/Autel/Parrot/FPV drones

First up, we've cranked up the power on this baby by optimizing the space design and doubling the power amplifier. That means your signal range gets a boost of over two times than DUO II, and is equivalent to a 5-10 with the stock antenna times. giving you the power to reach new heights and explore uncharted territories.

But that's not all! We've also thrown in a brand-new chip that works like a charm to enhance data transmission speed. In fact, it's a whopping four times faster than its predecessor, the DUO II.

And let's not forget about the Mu-Mimo technology that's packed into this beast. With dual transmission and reception capabilities, you'll experience improved signal strength and better overall performance, even in weak signal areas. crucial role.

But wait, there's more! The DUO 3 is not just limited to a specific frequency range. It's a versatile powerhouse that supports almost all 5G frequency bands, expanding from the previous 5.8G range to a wide 5.15Ghz–5.85Ghz range. That means compatibility with a wider range of wireless devices, so you can take your drone game to new heights.

We've also given the DUO 3 a makeover in the durability department. With a sleek all-aluminum alloy frame, this bad boy is built to withstand the toughest of adventures. Plus, the aluminum alloy structure optimizes heat dissipation, ensuring top-notch performance from the modules and chips.
