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"....
