Thank you for looking anyway. Chuck - AA5WG Cedar, MI 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. Chuck - AA5WG Cedar, Michigan |
