Hi Mike, 13.2 dBd sounds a little optimistic for a 4.7-foot UHF yagi. My older 9-foot Diamond A430-S15 yagi was rated at 12.7 dBd, and the 9-foot highly optimized M2 432-12EME antenna is rated at 14.3 dBd.
I'd ballpark a 5-foot yagi at around 10 dBd or so myself ... maybe they misprinted "dBi" ad "dBd"....
