How to Figure an Antenna's Length
- 1). Calculate a full wavelength antenna by dividing 936 by the transmission or reception frequency, measured in megahertz (Mhz). For example, the calculation for an antenna designed for 50 Mhz is 936/50 = 18.72 feet.
- 2). Calculate a 1/2-wavelength antenna by dividing 468 by the transmission or reception frequency, measured in megahertz (Mhz). For example, the calculation for an antenna designed for 50 Mhz is 468/50 = 9.36 feet.
- 3). Calculate a 1/4-wavelength antenna by dividing 234 by the transmission or reception frequency, measured in megahertz (Mhz). For example, the calculation for an antenna designed for 50 Mhz is 234/50 = 4.68 feet.
