1.2 GHz Cloverleaf Antenna tolerance

Question

I'm working on building my own Cloverleaf antennas, to work at 1.2 GHz, for the video system on my Quadcopter. At this frequency, what kind of tolerance am I looking at in terms of the length of the wire and the various geometric angles before I lose the advantage of this type of antenna? The calculator I used to find the length spit out a number in millimeters with, like, 8 decimal points after it, but after converting to inches, using a tape measure to measure it out, and trying to do the whole shebang in my dorm room bathroom (no hate on this please, it's fireproof I swear!), I only have about 1/8" - 1/16" accuracy. Is this enough?

Answer 1

IANARFEng... but

Wavelength of 1.2GHz in air is 25cm.

Often tolerances of λ/10 are acceptable (which is about an inch), so I'd think 1/8" would be OK.
