| in this very interesting article about measurement of loss in ant Tuners I do not understand how (Eq 1) on page 32 can be derived. The estimated loss in dB = 5 log ( (S1 +1)(S2+1)/9(S1-1)(S2-1)) Can anyone explain to me how this equation can be derived and under what boundary conditions? thanks, Hans DJ8UL |
