Small Transmitting Loop Antenna Calculator
Small transmitting loop antennas, commonly called magnetic loop
Experience with Loop Antennas for LF and VLF
It was like exploring a new world. I soon heard my first Amateur station on the 136 kHz band, G4GVC, followed by many others
A Wide Bandwidth Active Loop Receiving Antenna
Antenna adatta alla ricezione generale di banda amatoriale a onde corte. Questa antenna e' stata anche utilizzata con successo per la ricezione di segnali QRSS nelle bande di 20, 30, 40, 80 e 160 metri
Antenna Loop e adattamento di impedenza
Loop ad onda intera realizzata per la gamma degli 80 metri
T-Antenna for LF
I receive and transmit on 136 kHz 2200 m LF- band
