I'd like to be clear when I wrote earlier that a small transmitting loop is very inefficient.
I didn't mean they don't work, only that they only radiate a small part of the RF applied to them compared to a larger antenna. Consider a typical mobile "whip" antenna. They're terribly inefficient too but people get out with them, sometimes working DX when band conditions are good. Of course mobiles generally run more than the 10 watts or so a K2 produces, but contacts are made with QRP power and such antennas all the time. One way to make a given antenna "larger" is to use a higher frequency band. It's a matter of the antenna's size in wavelengths or fractions thereof that is important. That's why small antennas do so much better when the sunspots are active and the higher frequency bands are open.
