I believe in the magnetic loop antennas because I've heard them on the air
and have used them a little as well.
They perform as well as, or probably better than something like a mobile
antenna or screw driver or buddy poll etc.
I think they can probably perform as well as a dipole in the right operating
conditions and with good propigation as well.
They're relatively easy to build, or buy, take up little room, are somewhat
directional, and lend themselves well to qrp operation if that floats your
boat.
The key to qrp operation is to use the other guys big antenna lol.
