Helical LHCP 17.8 dBi Antenna — High-Performance Helical Antenna for 4.9-6.1 GHz

The Helical Antenna from [brand] is a compact and reliable helical antenna designed to provide stable directional communication in the 4.9-6.1 GHz range. Thanks to its helical design, the antenna demonstrates high gain of 17.8 dBi and supports left-hand circular polarization (LHCP), ensuring increased resistance to multipath signal propagation and better compatibility with equipment using such polarization.

Description and Advantages

This model is ideal for cases requiring directional coverage with a moderately narrow beam angle: the beam angle is approximately 35-40°, allowing for range and reception clarity without significant loss of beam width. The 22-turn design provides optimal helical characteristics for stable data reception and transmission over long distances. The housing material — plastic — ensures low weight and durability, while dimensions of 70*52*293 mm and a weight of only 81 g make installation simple and convenient on various platforms.
