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


Antenna switch arduino for icom IC-7300

Antenna switch arduino for icom IC-7300 A solution built around an arduino nano and one of the readily available four relay switching boards

50 MHz preamp Gain 26dB with the BFG135

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

30 Volt Computer Power Supply Stack

30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
