Hi Andy,
I can manage the maths, although the arithmetic always seems to go wrong, but 
not being a radio engineer, the formulae are not very familiar.
Can you point me to a good source.
John, G4CNN

Obviously not 1/R^6 roll off then !!!>Looking at the figures for 1km and 2km it 
appears to be more like 1/R^2
which is the rate of the radiation field decay - surely the H field should
fall off  faster than that ?

Very Curious.

Come on, there must be someone out there who understands and can apply
Maxwells equations :-)

To All from PA0SE

Here is the value of the near magnetic field up to 2km from the antenna.
