Micro RHCP 5.8GHz 3.5dBi RP-SMA Antenna, Red

Circular polarization matters for FPV video reception because it tolerates antenna orientation mismatches between the air and ground units far better than a linear antenna does, which is why RHCP has become close to a default choice for serious FPV flying. This micro version keeps that same RHCP benefit while shrinking the physical footprint down for tighter builds - micro quads, compact fixed-wings, or any frame where a standard-size antenna's bulk or weight is the limiting factor rather than its RF performance. The 3.5dBi gain figure sits in a sensible middle ground for this antenna's size class.
