WebHam Radio DipoleFormula. The formula to calculate the (approximate) overall physical length of a dipole is: Length (meters) = 142.58 / frequency (MHz) Length (feet) = 468 / frequency (MHz) The length of wire given by the formula is cut in half to make both sides of the dipole. The above formula gives an approximate result because the length at ... WebThe 6 meter dipole uses the same parts as the 10 meter model, less the 6-foot length of .5 inch tubing.
