You probably need to answer the questions you were asked before anyone could
advise on matching, like what's the length of the antenna?

Also, is this for pirate radio?

For 'educational purposes only', you could try these two programs. One
calculates the impedance at the feed-point of an inverted-L end-fed
antenna, and the other calculates the values of the L and C which you
need for an L-match tuner circuit.

endfeed.exe
l_tuner.exe (that's L-TUNER-EXE)

These - and many more wonderful programs - are available from this
