The MX²-Air takes the technology of the MX-Air and brings it to the X²-Air, with a few added tweaks. The pattern is considerably widened - at a cost of some frontal gain of course. (Don’t let anyone tell you that you can have both). The result is a range at 90° bore-sight that is nearly quadrupled.
Circularity in those areas is also considerably cleaner. This makes it the widest flight beam directional antenna available for FPV. Unlike the MX-Air, this antenna is not hemispheric and thus cannot be used as an omni when pointed upward. Use in a vertical orientation so the widest part of the beam is horizontal.
