Introducing the HELICAL 5.8GHz 12dBi LHCP (Left-Hand Polarization) Antenna, 12-Turn, Enclosed Type SMA from SkyReach. This circular helical antenna is designed for FPV applications and long-range sensing — it combines a compact design, reliable SMA connector, and high efficiency across the frequency range.

The antenna is designed to operate in the range of approximately 4900-6000 MHz with a consistent VSWR value below 1.3, ensuring low reflected losses and stable communication. The technical specifications also indicate a bandwidth of 4800-6000 MHz — this means broad compatibility with standard 5.8 GHz systems.

Implementations with various parameters are available for different needs: the PRO 12 version has a gain of 12 dBi and consists of 12 turns, while an improved version (mentioned for comparison, models like Penetrator V2) is described with a gain of up to 16 dBi and 18 turns. In its basic configuration, this antenna has left-hand circular polarization (LHCP), which enhances channel stability against interference and multipath.

For optimal long-range performance, it is recommended to combine the antenna with an antenna tracker — this is especially useful during extreme FPV flights and competitions.
