These antennas are called “Magnetic” because they work with the magnetic component of the electromagnetic field, in contrast to the common standard antennas that are in resonance only on the electric component.
Magnetic antennas can be very compact and are suitable for restricted spaces, does not require radials, can be placed close to the ground and can be used even indoor.
The Magnetic loop antennas usually feature a small bandwidth on their resonance frequency, but have the advantage of less harmonics.
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. The antenna can be put together in a short time and is cheap by Peter Parker VK3YE ex VK1PK
This loop it is small and light enough to carry while operating, it disassembles into small but rugged pieces that fit easily in a backpack or gym bag, and it can be tuned from 14 MHz to 30 MHz. This tunable magnetic loop antenna is my contribution to the well established art of amateur loop making. Can be tuned from 14 MHz to 30 MHz.
Our Magnetic Loop Antennas category has more than one hundred links to magnetic loops antennas. You will find either receiving small loops antennas and transmitting magnetic loop antennas projects.
The DXZone is the largest human created and maintained library of web sites dedicated to Amateur Radio, currently lists 20.000+ links organized into 600+ categories and subcategories. Ham Radio operators review new sites every day since 1998, for potential inclusion in the Directory, and to evaluate the best place to list them
