Magnetic Loop Antenna 30m, 20m, 17m, 15m, 12m, 10m Bands
A properly designed and constructed small loop of nominal 1m diameter will outperform any antenna type except a triband beam on the 10m/15m/20m bands

Magnetique 27-28 MHz
The critical part on this type of antenna always remains the variable tuning capacitor which is located at the hot spot of the antenna, zone where the impedance is the highest and the developed voltage very important
Practical Experiments with Magnetic Loop antennas
The magnetic loop is an unusual antenna, as with all smaller than perfect antennas, it has some drawbacks and some benefits
Probing the Magnetic Field Probe
Commercial and handcrafted probes similar to those shown are commonly used in EMC diagnostic work
Portable remote tunable magnetic loop anten
Covered HF bands: 40m to 10m 5.5MHz-29.8MHz Max. power 10W tested with an Yaesu FT-450AT Remote tunable through the coax
Small loop antenna
I have been experimenting with loops and found them to be very good Rx antennas. They have a useful null and provide a wonderfull drop in noise to bring the DX
