By pairing two of our famous X-AIR 5.8 you get more gain AND wider beam! Of course, there's a compromise which is reduced vertical beam width, but good good FPV don't happen up high :) A novel approach was taken to match the two antennas together and loose virtually no RF energy in the process. The result is an unmatched efficiency. Don't worry, at 45g only, you won't feel it on you goggles.
*Coverage where reception is at least equivalent to an omni.
**Coverage where at least 70% of the max range is obtained.
