Small magnetic loop antennas are gaining in popularity with radio amateurs who live in deed-restricted housing (HOAs and CC&Rs) or have very small urban lots with inadequate room to erect a full-length dipole antenna.

Magnetic loop antennas behave as a coil with a small radiation resistance and can be designed in several shapes to fit your operating conditions.  These antennas are small compared to 1/2 wavelength antennas, making them ideal for restricted spaces or for portable use.  Magnetic loop antennas can be designed for both receiving and transmitting.

In this post, we learn how to build 7 popular magnetic loop designs:

A magnetic loop for HF, covering frequencies between 3.5 and 10 MHz.  A fascinating article from Peter Parker (VK3YE).

Mag loop for 40m by ZL1BJQ.

Magnetic loop for 80-40 meters by HB9MTN.

40m magnetic loop antenna by CARC.

40m small magnetic loop antenna by hamradio.me.

Small magnetic loop project by KK5JY.

Each article is illustrated by helpful drawings, photos, and performance data.

The article also list several useful magnetic loop antenna calculators and a selection of magnetic loop tutorials from youtube.
