BiQuad Construction Templates


The two images below are templates to help you make BiQuad antennas.  You may be able print them directly from your browser with something like a Right Click, View Image, and then Print, if your printer and print driver support rescaling at the print step.  More likely, you'll need to save each image to your own hard drive (right click- save image as:) then re-open them in an image editor.  They are 300 dpi print ready PNG images (which is why they look so huge on your 75-92 DPI screen), and to exact scale when printed at 300 Dots Per Inch.  Most likely some helpful software will re-scale the printed image, and you'll need to fuss with your printer to make them the right size.  Try printing at 290 DPI, 300 DPI, 310 DPI, etc until they come out right.   If your software allows you rescale by percentage, that will also work.  Use a millimeter scale to compare with the printed scale, and adjust your printout until the two scales are identical in both length and width.

You'll need at least a hacksaw. or shears, a pipe cutting tool, pliers, a butane torch, a soldering iron, and a hand drill to make the antenna.  You'll also need some sheet metal, copper or otherwise, to make the backplane, and a bit of wire for the BiQuad.  Your big challenge and expense is in the cable connectors.
