Pete I have always used 2808/freq. in MHz = 1/4 wave in inches

Mark. I hope you don't mind me jumping in on this...
The reason the antenna is shorter is because the formula you have seen
is for the wavelength of a signal in FREE SPACE, which travels at the
speed of light. In a conductor, the signal travels at a fraction of the
speed of light (read on VELOC

On your web site, you list the length of each leg of your dipole at 20.3". I
went to an online site that will calculate the needed length ,
www.onlineconversion.com/frequency_wavelength.htm. Their conversion formula
gives a length range of 25.0" at 118 MHz to 22.0" at 134 MHz. Th
