Magnetic Loop Antennas
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.
Here we selected 5 interesting projects from our Magnetic Loop Antenna projects page
A indoor magnetic loop antenna that covers 20 17 15 12 and 10 meters band with a 3 meter lenght of 22 mm copper tube by G4IZH
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.
