Description

LA800 Super Loop Antenna – 10 kHz to 500 MHz The **LA800 Super Loop Antenna** is a high-performance, shielded loop antenna designed for wideband radio signal reception from **10 kHz to 500 MHz**. Manufactured by AOR, Japan, it is engineered for long-wave, medium-wave, shortwave, and other supported radio monitoring applications. Featuring a large 780 mm loop diameter and a rugged aluminium loop structure, the LA800 is designed to provide effective signal reception while helping reduce unwanted local electrical noise. Its active circuitry is housed in a weather-protected enclosure, making it suitable for outdoor installations. The antenna supports selectable tuning across five bands from 150 kHz to 30 MHz, while the remaining frequency ranges operate without alignment. With a 50 Ω impedance, a minimum gain specification of 20 dB, and a compact control unit, the LA800 is suitable for professional radio monitoring, HF reception, communication research, and RF signal observation. The supplied control cable, coaxial cable, power supply, and mounting hardware support convenient installation.
