Magnet loop for 80M - 40M
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 aerials for 1.8 MHz
Localised noise in the receiver can be reduced by using a small loop aerial. Shielded coax loops, unshielded loops and ferrite rod loops for 1.8 Mhz
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.

40m Compact 4-Square Antenna Compact 4-Square Antenna – EA5AVL The EA5AVL 40M Compact 4-Square Antenna was designed to provide excellent DX communications on the 40m band
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
