- 【Wide Frequency】 It is an active loop antenna that does not require external power supply. Working frequency: 0.1-180MHz, covering long wave, medium wave, short wave, FM broadcasting band, and VHF aviation band. The gain flatness within the working bandwidth is very good, providing approximately 20DB gain, with approximately 8.9DB gain even when operating at 450MHz
- 【Latest Version】 Adopting ultra-high frequency and low noise preamplifier devices, the latest version of the feed box has adjustable three-level gain, lower noise figure, and higher isolation. The SW antenna can tolerate -10DBM signal strength unsaturated. Adding an FMDX HF switch to the preamplifier can adjust the FM band gain (the FM strong signal region reduces the FM band gain and improves the HF band gain). The new version of the power switch is a touch switch, while the old version was a toggle switch
- 【Long Lasting Battery】 The K-180WLA Active Loop Broadband Receiving Antenna has a complete protection circuit for anti-reverse battery, over discharge, over charge, over current, and antenna terminal short circuit. The preamplifier box is equipped with a 3.7V 2750mAh lithium battery. The full power working time can reach 150 hours. MICRO USB charging port, compatible with mobile phone 5V charging head. The new version has added a low battery display
- 【Easy to Assemble】 With a small loop diameter of 55cm, this antenna is compact and easy to install on windows, balconies, terraces, or rooftops. It is ideal for broadcasting enthusiasts with limited space. The antenna's screws are made of 304 stainless steel for durability, and the front-end amplification box is fully waterproof, suitable for long-term outdoor use in harsh weather condition
- 【Suitable Models】The SDR Loop Antenna suitable for Desheng S-2000 PL-660 PL-880 ICOM R71E YAESU FRG-8800 and all other shortwave receivers. Especially suitable for use with SDR receivers
