Experience with Loop Antennas for LF and VLF at


The antenna is about 30 metres from the shack and at the highest point of the garden. The loop was wound with 36 turns and centre tapped. The inductance was found to be about 3 mH. 30 metres of RG58CU has a capacitance of about 3000 pF

Q- Multiplying Loop Antenna
This circuit is designed to be used in conjunction with the standard 4 foot square loop used in MW for long distance reception

Receive Loop Preamplifier
My idea is not to tune the loop, but simply transform the complex impedance

Receiving Loop theory
Multi turn wire loops are often used as low frequency receiving antennas. Applications such as geophysical research, oil exploration and survivable

Short Loop
The losses are not taken into account when calculating the values. Losses increase the bandwidth, but increasing the bandwidth in this way is total nonsense because the efficiency drops.
