For those that do not want to the effort to create a true Yagi antennae we found this two articles on creating a Cantennae, essentially a tin card cut to the appropriate length. The key is cut the length to 1/4 wave, half wave or full wave of the main carrier frequency of the signal you are trying to detect.

Cantennae construction basic:

Enter the can diameter and get the length of where to place the pick to detect the peak of the standing wave. from the end of the can.
