Yagi antennas give you gain in the direction they point in at the sacrifice of omnidirectionality.
I had an ole pool cue that I wanted to make into a tape measure yagi. The tape measure elements were not very cooperative and I wasn't prepared to drill. Will probably repurpose the pool cue into a yagi with metal screw elements in the future.
I later used PVC pipe and a drill to make a 2m and a 70cm tape measure yagi. The 70cm one has more elements.
