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.
