When I lived on a small lot in Maine, I was experimenting with indoor antennas (magnetic loops). Circulating currents and voltages are extremely high in this type of antenna. The tuning capacitor was (partially) a short stub of RG-58 coax. Worked fine barefoot (100W) but when I keyed up the linear (500W) it set the stub on fire. Flames, bits of burned polyethylene floating in the air... My wife was impressed :eek:
