Loop Antenna for 6m  ^pop - Indoor loop antenna for six meters band, project by Colen Harlow, G8BTK

A magnetic loop antenna for HF  ^pop - Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build. by Peter Parker VK3YE ex VK1PK

Multi Turn Magnetic Loop for 40/60/80 - The 40/60/80 is a portable loop that covers 80 meters with a high degree of compromise

GM3MXN Magnetic Loop Antenna - This article describes a loop usable from 7 - 21 mHz, using half inch copper tube 3 feet in circumference

160/80m Coaxial Receiving Loop Antennas  ^pop - Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.
