What is the approximate length, in inches, of a half-wavelength 6 meter dipole antenna?

To calculate the length of a half-wave dipole, you use the standard formula: Length (in feet) = 468 / Frequency (in MHz). The 6-meter band corresponds to a frequency of approximately 50 MHz. Plugging 50 into the formula (468 / 50) gives 9.36 feet. Because the question asks for the length in inches, you must multiply 9.36 feet by 12 inches per foot, which equals roughly 112 inches.
