Magnetic loop antennas Magnetic loop antennas are very compact HF antennas. If properly build they can be used for transmitting.I believe that if I would have used smaller pipe, the loop would not have worked so well on 80 meters. This is conjecture. I would compare this to the effect of a fat dipole or cage dipole. 80 Meter Magnetic Loop Antenna

Indeed, the single rectangle above 160 meters is probably a worse choice than its companion double rectangle. Like the 160-meter version of the double rectangle, the 80-meter antenna displays a slight gain over a single rectangle with relative insensitivity to the spacing of the two wires. 80 meter antenna | eBay Find great deals on eBay for 80 meter antenna.
