W8JI is correct.  I don't know where I picked up the
incorrect use of Voltage Node.  My Transmission Line
book refers to the voltage maximum as an "anti-node"
but I don't think we want to go there.  

Voltage Maximum and Current Maximum are the
clear, correct, and most readily understood terms
to use.

Voltage Feed translates to feeding at a Voltage Maximum
Current Feed  translates to feeding at a Current Maximum
