That's really neat. The ARRL Antenna book shows an array of untuned active loops too. I imagine y0u could combine these all into a Butler Matrix and get instantaneous steering.Loop antennas are preferred in some environments. Our main HF scanning receive antenna at the receiver site (NavCommUnit Key West) was a large Aperiodic Magnetic Loop Array similar to MODEL 4R8E13.
