Ensure maximum signal reception and transmission efficiency with this highly directional horn antenna. Designed for operation in the S-band (2050-2650 MHz), it supports simultaneous circular polarization (LHCP and RHCP), making it an ideal solution for professional communication systems, Wi-Fi bridges, and experimental setups where high quality and stable data transmission are required. It is used in electronic reconnaissance (SIGINT) and electronic warfare (EW) systems on the front lines, as well as for Simplex/Duplex control systems for UAVs, for remote drone controls, and guarantees clear and stable reception and transmission of linearly polarized signals in a critically important frequency range.
Purpose

Functions and Capabilities
The antenna provides high directivity and low side lobes, which minimizes the influence of external interference sources and focuses energy in the desired direction. Good matching (VSWR ≤ 1.5) with a 50-ohm feeder path guarantees minimal power loss and maximum system efficiency. Simultaneous support for circular LHCP and RHCP polarization is a key advantage for specialized systems using this type of signal.
For test ranges and specialized communication systems, such as reception in electronic reconnaissance (SIGINT) and electronic warfare (EW) systems on the front lines, as well as for Simplex/Duplex control systems for UAVs. The design ensures good matching with a 50 Ohm coaxial feeder path.
