Lumenier AXII Duality HD 2.4/5.8GHzDual-Band Antenna range test 01

It is more powerful than the DJI o3 air unit orignal antenna, goes further, and is more advantageous in penetrating. I'm really satisfied.

The test was conducted very leisurely up to 3.29km.
Perhaps more than 4km would be no problem, but under the current 5-inch mid-range conditions, longer distances would be difficult due to the limitations of the 5-inch li-po battery and the influence of wind.
