After googleing the formula to calculate impedance of a radio antenna, I came up with this formula Z = R + jX where X is reactance and R is resistance. I figured resistance could be measured with an ohmmeter. Then, it seems like there are two kinds of reactances, capacitive and inductive. The formula for capacitive reactance seems to be -1/2πfC, and the formula for inductive reactance appears to be 2πfL.
So my questions are: can I simply add the two reactances together? And how does this work if j is an imaginary number?
