They work best when the antenna is at least a quarter wavelength at the lowest operating frequency, 65' for 80m, for instance. To maximize the effectiveness, and have something useful down the line, you could build a small tuner. An L-network random wire tuner is probably the simplest matching network in existence, designs about on the net.
