Reference for formulat
I don't think dBi = 10log [9.9 * (D/λ) 2] is valid - is this for a parabolic antenna only? A reference would be good. Should this not be D/λ squared? --Wtshymanski 22:52, 7 April 2007 (UTC)

I cannot find the formula in books
I suggest removing the whole formula and perhaps adding a table of common antenna gains in dBi. Or we could leave all that to the antenna article. 130.230.101.50 13:28, 25 April 2007 (UTC)
