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

RockLoop Antenna  ^pop - A Compact antenna for 10.1, 14 & 21 Mhz Bands. A multiband portable antenna suitable for QRP operations.

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.

LF Receiving Loop - A really simple LF receiving loop antenna

Magnetic Loop antenna  ^pop - Why is an Magnetic Loop antenna so special, this antenna is picking only the magnetic part of the elektro magnetic radio wave. The big advantage of this antenna is that the electric interference from the big city have no influence on the received signal
