The JEM Engineering LPA-0618 is a handheld log periodic antenna engineered for ultra-wideband operation across 600 MHz to 18 GHz. Delivering flat 6 dBi gain throughout its entire frequency range, it provides consistent performance for spectrum monitoring, direction-finding, and cellular applications. The antenna features switchable vertical and horizontal linear polarization to accommodate diverse deployment scenarios. Its high-strength, low-loss plastic molded radome protects the active elements while maintaining electrical performance. The rotating pistol grip enables ergonomic field handling and rapid polarization transitions.
