COMPLETE CIRCUITS: Such as anti battery reverse connection, over discharge, over, over current, and short circuit are built into the active loop broadband receiving antenna.
^^ FINE WORKMANSHIP: The shell is CNC processed, with PCB design and high density copper 501.5 feed line, using premium materials to create a highly antenna with excellent performance.
^^ WIDE WORK RANGE: No external power supply is needed. It works in a frequency range from 50kHz to 500MHz, covering long, medium, short, FM broadcasting frequency range, and VHF aviation frequency range.
^^ HIGH GAIN: The gain flatness within the working bandwidth is very good. It provides approximately 17dB gain and still has about 7dB gain even when working at 450MHz.
^^ IMPROVED PERFORMANCE: The amplification board in the small loop antenna adopts an improved version of the LZ1AQ low noise amplifier, with a bandwidth from 50kHz to 500MHz and a gain greater than 10dB. It has a low input impedance ( 1.2 at 1MHz) to effectively reduce electric field interference. It is powered by a 12V linear power supply with a current not exceeding 150mA. ^^ ^^ ^^ ^^ ^^
