Aviation Converter Plus High-Impedance Amplifier: All-in-One
[1] With this device, you can down-convert the 118MHz-138MHz aviation band to the standard SW shortwave band that regular radios can receive, thereby enabling ordinary radios to easily tune into aviation frequencies.
[2] It supports conversion between a high impedance converter and an aviation converter.
It can achieve good matching and operation with various antennas such as magnetic loop antennas, passive small loop antennas, pull rod/whip antennas, etc., enhancing reception quality.
It can match high impedance antenna inputs for receivers or handheld transceivers with pearitic or standard 50-ohm inputs.
Compact and portable, it comes with a built-in 700mAh battery and USB-C charging port. It's truly an essential tool for staying at home, traveling, and listening to broadcasts!
