HELICAL 5.8GHz 10dBi RHCP 7-Turn Open-Type SMA Antenna

The HELICAL antenna from SkyReach is a high-quality solution for video signal and telemetry transmission in the 5.6 - 5.9 GHz range. This model is designed as a right-hand circular polarization (RHCP) helical antenna, ensuring a stable connection and increased resistance to reflections and multipath interference when used in drones, FPV systems, wireless video transmitters, and other 5.8 GHz radio systems.

Description and Advantages

This open-type antenna has a gain of 10 dBi, allowing for a focused signal over the required distance with less power loss. With a VSWR of less than 1.5, it features low reflected loss and good matching with the transmitter or receiver. The construction with a 1 mm enameled copper wire conductor ensures reliability and stable antenna operation in field conditions.

The antenna is suitable for integration into antenna kits, for replacing or upgrading standard antennas to more directional solutions with circular polarization. Thanks to its 7 turns and correct geometry, it creates a directional radiation pattern lobe with a beamwidth of approximately 39°, making it effective when aiming at a specific communication endpoint.

Installation and operation are simple: the helical design does not require complex adjustments, and the SMA connector ensures compatibility with a wide range of transmitters and receivers. RHCP polarization is particularly useful in FPV systems and when operating in conditions where signal reflections are possible, as polarization helps reduce interference and improve matching between the transmitter and receiver antennas.

This model is ideal for users seeking a reliable 5.8 GHz antenna with enhanced gain and stable characteristics. It combines simple design, durable materials, and excellent radio engineering parameters, making it an excellent choice for amateur and professional use.

If you need an antenna with clear operational parameters — frequency range 5.6 - 5.9 GHz, VSWR less than 1.5, 1 mm enameled copper wire conductor, 39° beamwidth, 10 dBi gain, 7 turns, and RHCP polarization — this HELICAL antenna from SkyReach fully meets these requirements.
