Default high earth resistance

Owen,

Are you referring to the coil alone? You are correct the coil accounts
for a significant part, probably between 4 and 8 Ohms.

I am measuring real values between 52 and 56 Ohms with 0j. This varies
mainly with moisture.

So let's say the total antenna is 12 Ohms. If the measured value is 52
that says the ground is 40. This puts us back to the original question:
why is the ground so high?

So, what do you think its impedance would be? 1500+j??


Duh, ??+j1500 is more like it.

Same outcome, it is probably accounting for 5 to 15 ohms of resistance that
you haven't included in your calcs.
