Use this 3-element diy Yagi antenna calculator to determine the dimensions for a standard 3-element Yagi antenna, including the reflector, driven element, and director. Enter the desired operating frequency to get optimal lengths and spacing for each element using established formulas. Perfect for ham radio operators and DIY antenna builders looking to optimize signal reception and transmission at a specific frequency.
3 Element Yagi Antenna Calculator Formula
- Reflector length = 0.495*2
- Dipoe length = 0.473* 2
- Director length = 0.440*2
- Reflector to Dipole spacing = 0.125*2
- Dipole to Director spacing = 0.125*2
λ = c/f
λ = Wavelength in meters
c = Velocity of propagation in air(3*10^8m/s)
f = Desired frequency in Mhz
