Helical Antenna LHCP 14 dBi — 12 Turns, 4.9-6.1 GHz

The Helical antenna from the manufacturer is a high-efficiency helical antenna designed for stable reception and transmission in the 4.9-6.1 GHz range. It belongs to the category: Antennas > Circular Antennas > Helical Antenna and is characterized by compact size and low weight, making it convenient for installation on drones, portable platforms, and external mounts where mass and dimensions are critical.

Key Features and Benefits

The 12-turn helical design provides an optimal balance between gain and beamwidth: the antenna gain is 14 dBi, and the beam angle is approximately 45-50°. The polarization is Left-Hand Circularly Polarized (LHCP), ensuring compatibility with equipment requiring left-hand circular polarization and reducing the impact of multipath reflections in complex environments. Thanks to its high gain and directivity, the antenna is suitable for FPV communication, radio communication, satellite applications, and wireless systems where range and signal stability are critical.

The SMA connector makes installation simple and compatible with a large number of transmitters and receivers, simplifying the integration of the antenna into existing systems. The plastic casing ensures a lightweight design — weighing only 54 g, and dimensions of 70*52*158 mm allow the device to be installed even on compact platforms without significant load.

The antenna is designed for use in conditions requiring medium directivity and stable communication: the combination of 12 turns and 14 dBi gain allows for focusing energy for longer signal reception/transmission, while controlling the beamwidth (45-50°).

• Operating range: 4.9-6.1 GHz — compatibility with popular FPV and wireless systems.
• LHCP polarization — reduced impact of interference and reflections.
• Lightweight and compact — 54 g and 70*52*158 mm for easy mounting.
• SMA connector — easy connection and compatibility with equipment.

The Helical antenna is suitable for both amateur and professional applications in FPV, radio communication, and satellite systems. It combines high efficiency, reliability, and ease of integration, making it an excellent choice for users who require high-quality left-hand circular polarization and high gain.

This model can be purchased in the Flash Army online store — the device has proven itself well in field and laboratory conditions, ensuring stable reception in the 4.9-6.1 GHz range.
