Let me add two more sites to the list.

AND

http://www.njqrp.org/n2cxantennas/halfer/index.html

As you most likely know, impedance whether simple or complex , is going to be relative to frequency, if you are concerned with a single band it should be fairly simple , but the more harmonically related bands you try for the more complex things become, an antenna analyzer IS the best tool to use here, a "GRID DIP METER" would be the next best .

Good Luck & 73, John
