Helical Antenna RHCP 17.8 dBi — 22 Turns, 4.9-6.1 GHz (Cable Length 300 mm)

Helical Antenna from the manufacturer — is a high-performance directional antenna for transmitting and receiving radio signals in the 4.9-6.1 GHz range. The helical design ensures stable right-hand circular polarization (RHCP), which significantly reduces the impact of multipath and reflected signals, increasing communication reliability in complex RF environments.

The model features 17.8 dBi gain and 22 turns, forming a narrow directional beam with a beam angle of 35-40°. Compact dimensions of 70*52*293 mm and a weight of only 81 g make the antenna ideal for mounting on unmanned aerial vehicles, stationary ground receivers, access points, and other platforms where low weight and minimal aerodynamic drag are important. The cable length is 300 mm, and the connector is SMA, ensuring wide compatibility with equipment from various manufacturers.

The casing is made of plastic, combining lightness with sufficient resistance to external influences. The helical geometry of the design allows for high-quality reception over significant distances even with a weak signal, making this model suitable for satellite communications, radio monitoring, specialized wireless systems, and amateur projects.
