In my view it does work as a loop antenna on 136 and 500kHz with the loop area being determined by the soil conductivity (lower conductivity, bigger loop area). The very fact that it is low-Q does suggest loss.
Hello Roger,
if
low conductivity = large loop area (A) but small antenna current (I)
high conductivity = small loop area (A) but large antenna current (I)
Would this result in A*I = constant ?
The radiation resistance of a loop is proportional to the square or the loop area (A). And the ERP is proportional to the square of the antenna current (I).
If A*I is a constant (independent or soil conductivity) this would mean that the ERP would no depend on soil conductivity ?
