73 to all, I would like to know your opinion about this: I can made a square TX loop for 470KHz of 7 * 3 meters (see picture) in the terrace of the building where I live (6 floors). the questions are

Buongiorno Mauro, a few months ago, I build a single turn loop, 0.7 m by 0.7 m, using very thick electrical copper wire. I resonated it on 160 m using a couple of beefy silver mica capacitors in para
