**ANT0103_OP 2–18 GHz Slant Polarization Omnidirectional Antenna**

The ANT0103_OP is a broadband omnidirectional antenna covering the full 2–18 GHz frequency range, designed for wideband surveillance, spectrum monitoring, and EW (electronic warfare) applications. Its slant polarization (typically 45°) provides a balanced response to both vertical and horizontal signal components, making it well-suited for intercepting signals of unknown or mixed polarization.

The antenna delivers omnidirectional coverage in the azimuth plane, ensuring 360° reception without mechanical rotation. Its compact, low-profile form factor enables rapid deployment in fixed, mobile, or temporary field installations. The wide instantaneous bandwidth eliminates the need for multiple antennas across the 2–18 GHz spectrum, simplifying system integration and reducing logistics burden.

Key features include low VSWR across the full band, consistent gain performance, and robust construction suitable for harsh operational environments. The antenna is commonly paired with wideband receivers, direction-finding systems, and signal analysis equipment in military and civilian spectrum management roles.

With its combination of broad bandwidth, slant polarization, and omnidirectional pattern, the ANT0103_OP offers a practical, single-aperture solution for modern wideband RF sensing and monitoring tasks.
