Description & Specification
LO-30M03GA1-NF Broadband Log Periodic Antenna
30 MHz - 3 GHz | Directional Reference Radiator | High Power 500W
The LO-30M03GA1-NF is a high-performance, wideband Log Periodic Directional Antenna (LPDA) expertly designed for professional RF testing across an extensive 30 MHz to 3000 MHz (3 GHz) frequency range. This laboratory-standard antenna features optimized internal geometries to achieve uniform directional radiation characteristics, delivering a stable gain profile from 3 to 11 dBi. Engineered for demanding transmission and evaluation setups, it safely manages continuous wave power levels up to 500 Watts (CW). Meticulously manufactured from robust 6061 Aluminum alloy framework and a high-durability Stainless Steel N-Female coaxial interface, it incorporates built-in DC Short lightning protection to safeguard valuable connected instrumentation. Designed and made in Taiwan, this industrial-grade antenna represents the ideal option for multi-band EMC/EMI compliance immunity testing, anechoic chamber measurements, and wireless spectrum monitoring networks.
