DRAFT !!! >> Building antennas from scratch and deploying an antenna analyzer will help reinforce the fun part of amateur radio. Learn design tools, test tools, and soldering techniques to create a useful product.
YAGI-Uda (YAGI)
YAGI antennas are seen everywhere. The design concentrates the beam. The more directors, the lower the angle, and more energy is focused.

Field of View FOV – Yellow = 5 element 70 cm 58 degrees. Blue is 11 elements, 38 degrees.
MMANAGAL – 70 cm 5 Element 445 MHz centered horizontal Yagi 3D far field
70 cm or 2 M Yagi & Calculator
2M 3-element tape measure Yagi
70 cm 5-element Yagi made with copper foil. Gain is 9.997 dBi 58 degree hor/vert
OPTIONS on Design: ARRL & DLUW6:
Reflector Spacing ARRL & 5 options under DLUW6
Director Spacing ARRL or DLUW6
dBd, then calculate the dBi Gain.
This Calculator for YAGI will produce the MMANA-GAL / 4NEC2, format file.
