So We have this thread going on the Loop on Ground antenna here: https://forums.qrz.com/index.php?threads/loop-on-ground-antenna.622669 It is not necessary to read that thread to answer this so I am starting a new thread. I am curious how to specifically test the impedance of my Loop on Ground. It has a transformer to convert from a theoretical 470 Ohm to 50 Ohm. But how can I use my coax based AA220Zoom antenna analyzer to measure the impedance of a loop antenna WITHOUT any transformer? I'd like to know the actual impedance of the loop so I can properly produce the transformer to convert it to 50 Ohm. Thoughts? Thanks.
