   W1MK and I wonder if anyone can point us to an authoritative reference for 
an answer to these two questions:

1.  An antenna model predicts a current of I amps at a particular segment on an 
antenna.  What is the maximum (peak) RF voltage V
that will be found at that location on the antenna?

   The practical application is to understand what voltage must be tolerated by 
any support (e.g., insulator and guy wire) attached
to the antenna at that point.

2.  Similarly, what is the maximum (peak) RF voltage V to be found at the tip 
of an antenna element?

   I'm sure there is a way to calculate this ... but I can't lay my hands on it 
quickly.
