Magnetic Loop Antenna Experiments - Building a magnetic loop antenna feels more like a small plumbing project as the principle building materials consists of copper water pipe and fittings that must be soldered ("sweated") together. Full details drawing and details here.

Thinking about Ideal Loops - Loop antennae have been used from ELF to UHF since the beginning of radiocommunications. At low frequencies, the main problem for loop antennae is to have enough sensitivity; the antenna being very small respect to the wavelength the collected energy is also small. To increase the output level the loop may be made resonant, so loosing it%u2019s intrinsic aperiodic characteristics.
