Product Description

Helical LHCP 12 dBi 10-Turn 4.9-6.1 GHz Antenna from the manufacturer is a professional-grade helical antenna designed for stable signal reception and transmission in the 4.9-6.1 GHz range. The helical design provides left-hand circular polarization (LHCP), which enhances communication stability in high-interference environments and minimizes losses when interacting with other antennas designed for the same polarization.

The antenna features a 12 dBi gain, which helps focus energy for long-range communication, while a 45-50° beam angle provides an optimal balance between coverage and range. The model is equipped with 10 turns of the helix, improving selectivity and signal stability over long distances. Compact dimensions of 70*52*135 mm and a weight of only 46 g make the antenna easy to mount and integrate into various structures and carriers.

Advantages

• High 12 dBi gain for effective long-distance transmission.
• Left-hand circular polarization (LHCP) for enhanced compatibility and reduced losses during cross-polarization interaction.
• Helical design ensures stable reception in complex, high-interference conditions.
• Compact dimensions of 70*52*135 mm and low weight of 46 g — easy mounting and integration.
• Standard SMA connector for universal connection to most transmitters and receivers.

Technical Specifications

The Helical LHCP 12 dBi antenna from is ideally suited for drone systems, radio communication, real-time video transmission, telemetry, and satellite channels where circular polarization and signal stability are crucial. It ensures reliable data and command transmission in commercial and amateur applications, especially where energy focusing and minimization of reflection and interference effects are necessary.

The antenna's materials and construction guarantee long-term operation, and the standard SMA connector makes it compatible with most transmitters and receivers on the market. Before purchasing, pay attention to compatibility in terms of polarization (LHCP) and connector (SMA) to achieve maximum communication quality.
