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"....

Hi guys,  I'm looking at putting an unused Cushcraft A430-11s antenna into service. The clained gain is 13.2dBd and a front to back ratio of 20dB. This seems good for a 4.7 ft long 11 element antenna. Has anybody any knowledge of how good it really is? Regards Mike G3LGR
