Small Magnetic Loop Antenna Project

WA4 MNT Small Transmitting Magnetic Loop Antenna Project 30m, 20m, 17m, 15m, 12m, 10m Bands With the solar cycle improving, I wanted to build an efficient HF Antenna for the upper bands that I could easily throw in the trunk of the car and operate quickly with a minimum of setup time. I decided on a Small Magnetic loop Antenna after researching the subject on the web and reading the following statement from VK5 KLT s article on Small Magnetic loop antennas. A properly designed and constructed Small loop of nominal 1m diameter will outperform any Antenna type except a tri-band beam on the 10m/15m/20m bands, and will be within an S-unit (6db) or so of an optimised mono-band 3-element beam that s mounted at an appropriate height above ground.

between the radio and antenna. I am not an antenna theoretician; my expertise is in mechanical design. I have attached all my detailed .pdf’s and defer to the complete VK5KLT “An Overview of the Underestimated Magnetic Loop HF Antenna” article at the end of this document for the theory of operation.
