Tony,
I cant think of a simple way... I modeled it on Eznec and came up with a
feedpoint Z of
22.37 -j442. From some software of my own, that Z with 50 watts applied
will have a
voltage = 661.65, current = 1.5 amp, and phase angle = -1.52 radians. I may
have messed up the model
but Im sure of the voltage/current at that Z

Subject: [TowerTalk] Voltage at feedpoint
Is there a simple way to calculate the voltage at the feedpoint? As an
example, say I wanted to find out what kind of voltage I should expect at
the feedpoint of a 40M dipole when it is being driven on 60M with 50W. My
concern is that I don't screw up the balun that is used at the feedpoint or
having any arcing issues.
Tnx
N2TK, Tony
