"L" network problem solver?

[w5tvw]

Somewhere on the web I found a program that you feed in the vector impedance
of an antenna ( say 123-j58 ohms) and it will give you the values of an "L"
network to match this to a 50 ohm transmitter.

Anybody recall where one of these "calculators" is on the internet?

I had one on my former computer but the datat was lost when a big lightning
bolt took out the machine!

This looks as if it'll do the job:

Antenna modeling software MMANA has got such a calculator built in.

TLW, the transmission line calculator that comes free with the ARRL
Antenna Book, does that very nicely.
