Hi to all:

Can anyone help locate the following 1965 73 Magazine article titled "Tuned Feeders Fowever - Nasty Black Snake" by W5DWT, pg 24.

Hi Don (K4KYV):
Thank you for looking anyway.

Oh yes, Don, do you know how to calculate for theoretical needed inductance for the tank output coil of a link antenna coupler?  The coupler would have the output capacitor electrically placed in the middle of the tank coil providing series/current tuning of antenna system. 

And, if the antenna system is 3.5 wavelengths long, at frequency, I would need to add 3/4 wavelength arrive at 5 wavelengths.  This is the next odd 1/4 wavelenht muliple that would be low impedance for current/series feed of antenna system.  I want to series feed the antenna system.

How do you calculate the additional 3/4 worth of inductance needed?

Thank you for your consideration.
