 Posted: Thu May 19, 2011 3:59 pm    Post subject: element lengths of an Antenna what about L = 468/f MHz? To calculate the length (in feet) of a quarter-wavelength vertical antenna Divide 234 by the antenna’s operating frequency (in MHz) [234/f (in MHz)], is that right ? Also does the thickness of the wire matter? what about what kind of wire it is does the matter?
