Hello group, many thanks to all who replied on my request. One more thought : if the loop would be very good (= low loss, let's say about 0.5 Ohm) this would mean high current and thus also rather hi
Hello Dave, A Q of 20 seems very low, it would mean that losses are as high as 5 Ohm (Q = XL/R). But maybe Q is calculated based on the Rrad of 2.5 Ohm, that would explain the low value. 73, Rik I ha
I am about to put up a transmitting loop antenna. Dimensions will be 23m long and 15m high. Thanks to Dick (PA0SE) I could achieve a wheel of 7mm litz wire, so wire losses should be minimized (about
Dear Rik, LF Group, I reckon your loop will have inductance of the order of 100uH, so with the kind of currents you are hoping to achieve, the voltage on the loop will reach at least a few kV. With t
John A. says: Last winter, when I ran the 50ft perimeter loop, I found that laying out several 40 foot strips of chicken wire made no difference on the impedance bridge readings. That antenna was 15
Bill, I suggest the transformer approach because when the loop conductor will have some leakage current to the trees (it's small Mal <G>) and this will be minimized if the loop is allowed to float re
