[Improved Performance] Features LZ1AQ low noise amplifier with a bandwidth from 50kHz to 500MHz and a gain greater than 10dB. Low input impedance effectively reduces electric field interference. ^^ [Wide Work Range] Works in a frequency range from 50kHz to 500MHz, covering long, medium, short, FM broadcasting, and VHF aviation frequencies. ^^ [High Gain] Provides approximately 17dB gain within the working bandwidth and maintains about 7dB gain even at 450MHz, ensuring strong and clear reception. ^^ [CompleteCircuits] Built-in anti battery reverse connection, over discharge, over, over current, and short circuitensure and of the antenna.
^^ [Fine Workmanship] CNC processed shell with PCB design and high density copper feed line ensure excellent performance. ^^ ^^ ^^ ^^ ^^
