HELICAL 5.8 GHz Antenna — 12 dBi, RHCP, 12 Turns, Enclosed Type, SMA

We offer a high-quality Helical circular antenna from the manufacturer SkyReach, designed for long-range FPV communication and challenging signal conditions. This model is an enclosed helical antenna with right-hand circular polarization (RHCP), ensuring stable reception and interference resistance.

Custom manufacturing is available: we adapt connectors, cable length, and other parameters to meet customer requirements. The technical description provides all key device parameters for correct selection and system integration.

Please note: the description also mentions the Penetrator V2 model with an impressive 16 dBi gain — this is a different antenna version for maximum range. The current PRO 12 Helical model, in the configuration presented here, has a gain of 12 dBi and is optimized for a balance of focus and signal stability.
