Introduction To Magnetic Loop Antennas
This style of antenna is often used for direction finding and has a sharp reception null when turned broadside to the incoming magnetic field

Experimental eight-shaped loop for HF
The idea behind the double loop is that two properly polarised magnetic fields enhance each other and because the two loops are in parallel
Hula Hoop LoopThe concept of the Hula Loop came after many years of building medium wave loops of varying size
Hoop Loop Ultralight Radio Antenna
Loop is built on a 23-inch quilting hoop, the base is seven inches in diameter and is sold as the mounting plate for clocks
How to build for 14 MHz magnetic loop antenna
20 Meter Loop Antenna it's such a simple project and requires no special order components. In fact, all of the components save, perhaps, the antenna connector can be purchased at a DIY store
HF Receiving Loop
My capacitor wasn't large enough to take the loop down to 80 metres, at least not without adding more turns

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
