Yeah, I've been wanting to make a high order yagi antenna for FM for a long time but have been daunted by the construction. All I need with this is a piece of cardboard, a ruler and a nub to compress the traces when dry for better conduction. :-)

They did some experiments with HF antennas like for WiFi or cellular and it didn't work so well but I think there is a HF limit with it that FM should fall far below.
