M0GVZ,

I see how your testing is set up.  But please explain to me how you arrived at the choking impedance at the corresponding SWR's.


EG;

Choking impedance = 100 Ohms, SWR = 1.5:1

Choking impedance = 250 Ohms, SWR = 1.2:1

Choking impedance = 500 Ohms, SWR = 1.1:1

Choking impedance = 1k Ohms, SWR = 1.05:1

Choking impedance = 2k Ohms, SWR = 1.02:1


I'm having a problem seeing/understanding how you did that.
