Use with a ground loop antenna for RF reception (about 100 feet off the ground). Works very well with rtl-sdr. You can pick up wspr from around the world with a preamp installed.

It's BALUN and he's acting like one. Most commonly, baluns have a 1:1 and 1:4 ratio and are used to isolate lines or dipole antennas. At higher values like 9:1 or 49:1 the core is wound as UnUn for use with random and half-wave wire antennas where ground or counterpoise are not as critical. What does that mean for you? This…
