WebThe basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters . The inverted Vee antenna legs will be longer by 2 - 6% from those of the horizontal antenna depending on the angle. WebThis antenna wavelength calculator can be used to determine the physical length of an antenna’s electromagnetic wave in free space. This can be useful for determining antenna ground plane requirements, antenna spacing requirements to prevent coupling in for multi-antenna systems, or other situations where the antenna’s wavelength is needed. WebThe basic formula for determining the length of a center fed, half-wave wire Dipole or Inverted Vee antenna is: 468 ÷ freq (mHz) = Length (feet). This formula takes into consideration the capacitive "end-effect" from insulators which shortens the physical length requirement for the equivalent electrical length.
