Hi Group.
I sould someone to add.

only for elevated conterpoise. The formula is:


R=(1/(pi*s) * [(1/la)*ln( (H+h)/(2*H) ) + (1/lc)*ln( (H+h)/(2*h) )]

where
la - antenna length,
lc - conterpoise length.
Other notations are the same then previously.

If lc=la then the formula obviously became the same then previous one.

If lc >> la the formula is not right. Charge distributing seems to be not
homogenious. Sorry, I have not notice some problems at first.
But if lc ~< la may be OK. It's should be tested and may be the formula
should be modified. PSE do not use it now. Sorry again.
