Formulas for Calculation

• Vertical Antenna: Length = 234 / Frequency (MHz) (for quarter-wave)
• Dipole Antenna: Length = 468 / Frequency (MHz)
• Yagi Antenna: Driven element length depends on design, typically close to dipole length.
• Half-Wave Antenna: Length = 468 / Frequency (MHz)
• Quarter-Wave Antenna: Length = 234 / Frequency (MHz)
