Roy quite reasonably wrote, "If you really had measured the dipole
impedance and if the reactance was enough to bother with, the answer to
your question would be to put it in
series."

You can instead put capacitance in parallel with the nominal 65+j16 (if
that's what it is) to make it non-reactive, though doing so will raise
the resistive impedance, and thus not improve the SWR rel. to 50 ohms
as much as series capacitance (a pair of balanced caps...). But if you
increase the shunt capacitance beyond what's needed to cancel the
reactance, and then add series inductance, you can get to a "perfect"
match to 50 ohms. (There are, in general, many ways to match one
impedance to another, by using various combinations of inductance,
capacitance, transmission line stubs and transmission line series
sections.)

But first beware of the pitfalls Roy mentioned, and understand if you
really need additional matching.
