King Mudduck,
The whip is only half of the antenna, you need to make the other half. The other half amounts to a few radials (at least one). Then you wind up with a 1/4 wave groundplaneantenna, or a vertical dipole.
The radial thingy can be as simple or as eleborate as you want, close to equal results either way. Or, just make the whole thing out of wire and hang it from something (even cheaper!). [Got a metal fence that runs under a tree with a branch at least 9 - 10 feet above the fence? It'll work.]
