Variometer Design
A variometer consists usually of two coaxial coils, connected in series, where the coils relative position can be varied in some way
VLF The stealth antenna
the passion for radio listening on HF and lower band, down to VLF
Vertical antenna with inductive toploading
136kHz antenna by placing a part of the loading coil at the top of the vertical part
Very Low Frequency Receiver
Very low frequency or VLF is the ITU for radio frequencies RF in the range of 3–30 kHz, corresponding to wavelengths from 100 to 10 km, respectively
