The AxisFlying 5.8G SMA Antenna is a high-performance antenna designed for use in the 5.8GHz frequency band. It comes in two versions: LHCP (left-hand circular polarized) and RHCP (right-hand circular polarized). These types of polarization are used to reduce interference and increase signal quality in the 5.8GHz frequency band. It has an SMA connector which is a type of RF connector commonly used in wireless communications and other low-frequency electronic devices. The Antenna is suitable for use with a wide range of RC vehicles, including drones, cars, boats, and aircraft.
