Berehynia drone range extension systems with Kvazar amplifiers (2.45 – 5.8GHz)

Brand: Kvazar Sat. A complete system for significantly extending communication range and ensuring reliable video and command channel relay for FPV drones at 2.4 GHz and 5.8 GHz frequencies. At the core of the solution is the Kvazar 2.45 – 5.8 GHz 2.2 MIMO Antenna, which combines two separate X-polarized antennas in one housing, providing high signal stability in the flight direction and increased resistance to interference.

The antenna has a stated gain of 12 dBi at 2.4 GHz and, according to the manufacturer's description, up to 10 dBi at 5.8 GHz; at the same time, the specifications block indicates a practical gain value at 5.8 GHz of 6.0 dB. Therefore, when designing the system, both indicators should be considered as information on operating modes and actual measurements. The beamwidth is stated as 60°/45°, the Voltage Standing Wave Ratio (VSWR) is no more than 1.45, and the cross-polarization discrimination in the 1-dB zone is 20 dB.

Specifications

The package includes two 4W amplifiers with their own battery pack and charger, allowing for the deployment of an autonomous amplification section on a tripod to achieve stable long-range communication without constant external power connection. The 20m dual N–N cable (Cavel WL400) and N→SM and IPEX→SMA adapters ensure easy integration of the antenna with existing radio systems and control remotes.

This system is ideal for FPV drone video signal and command channel relay tasks: it increases range, makes communication more stable in challenging conditions, reduces the likelihood of signal loss, and improves data transmission quality over long distances. During installation, consider the operating temperature limits (-45°C … +50°C) and permissible wind speed (up to 20 m/s), as well as the antenna's dimensions and weight for proper mounting on a tripod or stationary structure.

To maximize the effectiveness of Kvazar amplifiers, it is recommended to verify actual gain values in field conditions, taking into account the difference between factory data and practical measurements at 5.8 GHz (6.0 dB in the technical block and up to 10 dBi in the manufacturer's description). Integration of the kit with your equipment is ensured by N–SM, IPEX→SMA adapters, and the included cable.
