Helical RHCP Antenna 18 dBi 32 Turns 4.9-6.1 GHz — a high-performance helical antenna from the manufacturer, designed for reliable signal reception and transmission in challenging conditions. Combining compact dimensions with powerful gain, this antenna ensures stable communication over significant distances even with a weak signal level.

Description and Purpose

The Helical (spiral) design forms right-hand circular polarization (RHCP), which reduces the impact of reflected signals and improves reception quality. The antenna is optimal for applications in radio communication, satellite systems, unmanned platforms, and other wireless networks where signal stability and directionality are critical. The lightweight plastic casing makes the device durable and easy to install, while its dimensions of 70*52*293 mm and weight of 117 g allow for easy integration into portable and mobile solutions.

Advantages and Features

The helical shape and optimal number of turns (32) provide high directionality and radiation stability, making the antenna an ideal choice for medium to long-range operation. The 18 dBi gain significantly boosts signal reception/transmission, and right-hand circular polarization reduces the impact of multipath effects and interference, enhancing compatibility with RHCP receivers.

The SMA connector ensures simple and reliable connection to a wide range of equipment, from FPV transmitters to ground receiving stations. The plastic casing guarantees resistance to mechanical stress without excessive weight increase, which is important for unmanned aerial vehicles and portable kits.

Operating Recommendations

For maximum efficiency, install the antenna in an open area with minimal obstructions in the signal path and direct the main beam towards the signal source. Ensure the reliability of the SMA connection and, when used outdoors, take measures for moisture protection and sealing of contacts. The compact dimensions of 70*52*293 mm and weight of 117 g allow the antenna to be mounted on stationary installations, mobile platforms, drones, and portable receivers.
