Broadband Magnetic Loop Antenna with Amplifier, 0.1–180MHz

Wide Frequency Coverage from 0.1MHz to 180MHz

This broadband loop antenna supports reception across long wave, medium wave, shortwave, FM, and VHF aviation bands, making it a highly versatile option for radio enthusiasts and SDR users. Ideal for both general broadcast listening and advanced signal monitoring.

High-Gain 20dBi Active Amplifier

The built-in low-noise preamplifier ensures a 20dBi gain over most of the frequency range, maintaining up to 8.9dBi even at 450MHz. The amplifier features gain balance across frequencies and includes an FMDX/HF gain switch for optimal performance in strong FM signal areas.

Double-Shielded High-Quality Feeder Cable

A 10-meter aluminum platinum and copper double-shielded feeder minimizes signal loss and electromagnetic interference. The dense mesh design improves overall shielding performance and signal integrity, even in electrically noisy environments.

Self-Powered with USB Charging Convenience

Powered by a built-in 3.7V 18650 lithium battery, the unit operates without external power. Charge easily via Micro USB with any standard 5V Android charger or cable, ensuring flexible and portable use.

Rugged Design for Long-Term Outdoor Use

The antenna and amplifier housing are constructed with numerical precision and 304 stainless steel components, providing waterproof protection and resistance to corrosion. Suitable for balconies, terraces, rooftops, or windows.

Compatible with Multiple Receivers

Comes ready to connect with SMA, BNC, and 3.5mm interfaces, making it compatible with popular receivers like Desheng S2000, PL-660, PL-880, ICOM R71E, YAESU FRG-8800, and SDR devices. Additional adapters may be required for other interfaces.
