No holes in walls, no ground radials, high noise from switching power supplies. The Moxon Solution: Build a small magnetic loop? No – build a portable Moxon for 15m or 10m and mount it on a photography light stand inside a balcony or on a push-up mast clamped to a deck railing. Because the Moxon has deep nulls on the sides (off the tips of the rectangle), you can orient it to null out a noisy neighbor’s plasma TV or a specific apartment building’s switching supply.
