Magnet loop for 80-40 meter


Planned Hinge-Capacitor, Remote Control via Motor-driven Excenter, Plates 25x25cm, Spacing at 80m = 625 cm2/128pF = 4.88mm,Spacing at 40m = 625cm2/14pF = 44.64mm

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.
