Steve,
It seems to me that the current difference can only
be due to
1) Radiation from the coil (unlikely)
2)LOSSY capacitance from the coil/feeder to
surroundings.
I found that my Ant. current varied about 10%
depending on wether it was raining (or have recently been raining). I thought at
first that this was insulator leakage or wet trees,but eventually
identified discovered that the brick wall close to my loading coil was the
culprit.I now have a large sheet of alluminiun against the wall which is
grounded.So although there is still a lot of capacity from the coil to this
screen it is not LOSSY. Now there is no variation,or at least very little. I
hope this helps.
73s Laurie.
