Yagi design program for vhf/uhf

"We need one Zebra!"

This Javascript calculator will calculate dimensions for a horizontal or vertical yagi. It outputs x,y,z coordinates in mm, for use in optimization programs like EZNEC and MMANA-GAL. (MMANA-GAL uses meters not mm, so until i change this, you will have to convert from mm to m.) Please report bugs or errors to orrin.winton at gmail.com.

Also note that this program does not give you the tools to design a feedpoint balun. Hint: one kind of balun for matching is a simple half-wave coaxial balun (see diagrams below).

Enter frequency in MHz (first box), number of elements (2nd box), height above ground IN METERS (3rd box), and type horizontal or vertical (all lower case) for the polarization, then hit 'calculate.' For a new antenna, or to change values, be sure to hit CLEAR and start from scratch.
