F/D Ratio similar .3575 BSC621 10' Bud ???

[phpinfo]

The BSC621-2 doesn't have any F/D ratio markings on it, but my ratio is 0.357575.

Does anyone have a similar ratio and if so can you measure from your scalar ring to the tip of the feedhorn and tell me how much it is, in inches? 1/2", 3/4" ?????

10' Winegard Bud
22" depth
F/L = 40.9 - ~1/4" on BSC621-2 ??

those numbers sound close to my 10 ft dish
mine is set 1/2 inch below the scaler and could be closer to 5/8 of an inch below.

your F/L should be about an 1/8 inside the feedhorn
