Status

These have already been created, but not finished. Currently, they need a backplane and a connector attached to them.

Details

The theoretical gain is ~22dbi and theoretical beam width is < 10 degrees. Practical gain and beamwidth are unknown as it has not yet been tested. These antennas have the amazing property of being able to lock onto any linearly polarized signal regardless of polarization. They can not pull in a signal that has been circularly polarized in the opposite direction.


Materials

VERY large guage solid copper wire (god only knows how much power you can put into these things)

2" diameter PVC pipe

other various PVC parts

History

The pair of antennas was originally created LONG before the make shop came about. I was bored and wanted something I could wifi-snipe with, so I decide to make my own.
