vlf antenna

A VLF loop by IK0VVE - This antenna was born from the demand to use a loop for vlf operations in portable posting, avoiding the aid of long wires to stretch.

Advanced active VLF Loop - Article on using loop antenna in very low frequencies

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.
