I see, this is not a wire antenna though. Your formula is close enough to 585/f in the real world anyway.
Thank You,

that formula only applies to antennas in free space.

I know the difference. The real world difference, at the adjustment stage is noise.@ a frequency of 27.205 mhz. the difference is 13.25 inches. it's easier to shorten an element if length is excessive than it is to add length to an element that is too short.
in free space: 585 / 27.205 = 21.50' or 258.04"
over real earth: 615 / 27.205 = 22.60' or 271.27"
learn the difference.
